### SIGNAL

This strategy allows you to integrate approved external signal provider's signals or your own TradingView signals. SIGNAL is true when ProfitTrailer receives a correctly formatted signal from an external source. If you have notifications turned on these will trigger when a signal buy or sell is made.

If using SIGNAL either an approved external provider signal or your own TradingView signal is required.

These Signals are created outside of the ProfitTrailer product, see this page for details on how to integrate with signals

**The Numbers**

Valid Values: no additional buy or sell values are associated with this strategy as everything needed to signal a trade is derived from the signal being received from the external source. Your other buy and sell settings criteria still need to be met.

**Examples**

`DEFAULT_A_buy_strategy = SIGNAL`

→ buy will happen when a valid signal is received and your other settings buy criteria have been met. i.e. min_buy_volume

`DEFAULT_A_sell_strategy = SIGNAL`

→ Sell will happen when a valid signal is received and your other settings sell criteria have been met. i.e. GAIN percentage profit has been achieved

**Notes:**

- If using SIGNAL either an approved external provider signal or your own TradingView signal is required. These Signals are created outside of the ProfitTrailer product, see this page for details on how to integrate with signals
- Signals are not part of your ProfitTrailer product license and require a separate paid subscription to either an approved supplier's signals service and/or the TradingView integration service. These subscriptions are available for purchase from the ProfitTrailer Shop.

### LOWBB

This buy strategy is true when current ask price goes below the LOWBB threshold you specify.

This sell strategy is true when current bid price goes above the LOWBB threshold you specify.

BB values are percentages of the BB width. Width = HIGHBB - LOWBB and a `buy_value`

/`sell_value`

of +/-10 represents 10% of this width.

For a coin to be bought/sold using LOWBB, the ask/bid price must be less than the value of the LOWBB price multiplied by (1 + `buy_value`

/`sell_value`

expressed as a percentage).

**The Numbers**

Valid Values: positive or negative decimal values

Frequent Values: from 100 to -100

100 = 100% of the BB width above LOWBB. i.e. on the HIGHBB line

50 = 50% of the BB width above LOWBB. i.e halfway between HIGHBB and LOWBB

0 = on the LOWBB line

-45.25 = 45.25% of the BB width below LOWBB

-235 = 235% of the BB width below LOWBB

The lower the value the more conservative it is for buying and more aggressive it is for selling.

**The Formula**

negative `buy/sell_value`

Buy Price < LOWBB - ((HIGHBB - LOWBB) * ABS(buy_value)/100) Sell Price <= LOWBB - ((HIGHBB - LOWBB) * ABS(buy_value)/100)

positive `buy/sell_value`

Buy Price < LOWBB + ((HIGHBB - LOWBB) * ABS(buy_value)/100) Sell Price <= LOWBB + ((HIGHBB - LOWBB) * ABS(buy_value)/100)

**The Parameters**

`BB_std`

`BB_candle_period`

`BB_Length`

**Examples**

`DEFAULT_A_buy_value = 20`

→ buy zone begins 20% (of width) above LOWBB line. Ask price must be less than this value. `DEFAULT_A_buy_value_limit`

must be less than 20 including negative numbers if used.

`DEFAULT_A_buy_value = 0`

→ buy zone begins right on top of the LOWBB line. Ask price must be less than this value. `DEFAULT_A_buy_value_limit`

must be less than 0 if used.

`DEFAULT_A_buy_value = -10`

→ buy zone begins 10% (of width) below LOWBB line. Ask price must be less than or equal to this value. `DEFAULT_A_buy_value_limit`

must be less than -10 if used.

`DEFAULT_DCA_B_sell_value = -10`

→ sell zone begins 10% (of width) below LOWBB line. Bid price price must be less than or equal to this value. `DEFAULT_A_sell_value_limit`

must be less than -10 if used.

→ Use **TradingView** to visualize **LOWBB/HIGHBB** with this indicator.

### HIGHBB

This buy/sell strategy is true when current ask/bid price goes above the HIGHBB threshold you specify.

BB values are percentages of the BB width. Width = HIGHBB - LOWBB and a `buy_value`

/`sell_value`

of +/-10 represents 10% of this width.

For a coin to be bought using HIGHBB, the ask price must be greater than the value of the HIGHBB price multiplied by (1 - `buy_value`

expressed as a percentage).

For a coin to be sold using HIGHBB, the bid price must be greater than or equal to the value of the HIGHBB price multiplied by (1 - `sell_value`

expressed as a percentage).

**The Numbers**

Valid Values: positive or negative decimal values

Frequent Values: from 100 to -100

100 = 100% of the BB width below HIGHBB. i.e. on the LOWBB line

50 = 50% of the BB width below HIGHBB. i.e halfway between HIGHBB and LOWBB

0 = on the HIGHBB line

-45.25 = 45.25% of the BB width above HIGHBB

-100 = 100% of the BB width above HIGHBB

Lower values are more conservative for buying and higher values are more conservative for selling.

**The Parameters**

`BB_std`

`BB_candle_period`

`BB_Length`

**The Formula**

negative `buy/sell_value`

Buy Price > HIGHBB + ((HIGHBB - LOWBB) * ABS(buy/sell_value)/100) Sell Price >= HIGHBB + ((HIGHBB - LOWBB) * ABS(buy/sell_value)/100)

positive `buy/sell_value`

Buy Price > HIGHBB - ((HIGHBB - LOWBB) * ABS(buy/sell_value)/100) Sell Price >= HIGHBB - ((HIGHBB - LOWBB) * ABS(buy/sell_value)/100)

**Examples**

`DEFAULT_A_buy_value = 20`

→ buy zone begins 20% (of width) below the HIGHBB line. Ask price must be greater than this value. `DEFAULT_A_buy_value_limit`

must be less than 20 (i.e a higher price)including negative numbers if used.

`DEFAULT_A_buy_value = -10`

→ buy zone begins 10% (of width) above the HIGHBB line. Ask price must be greater than this value. `DEFAULT_A_buy_value_limit`

must be less than -10 (higher price) if used.

`DEFAULT_DCA_B_sell_value = 0`

→ sell zone begins right on top of the HIGHBB line. Bid price price must be greater than or equal to this value. `DEFAULT_A_sell_value_limit`

must be less than 0 if used.

→ Use **TradingView** to visualize **LOWBB/HIGHBB** with this indicator.

### GAIN

**Note:** If GAIN is not used as a sell strategy, then trailing profit settings cannot be used. Be aware that allowing other strategies to sell regardless of current price may result in coins being sold for a loss.

This sell strategy is true when current profit is greater than or equal to `sell_value`

.

GAIN acts as the minimum profit level you are targeting. If you set a negative value coins can be sold for a loss.

The `sell_value`

is a percentage of profit that must be reached. When calculating the price required to make this amount of profit the bot also accounts for fees (on Binance the bot assumes the full fee, not the BNB discounted fee.)

The Profit % (P%) column in pairs and DCA Logs shows the fee corrected current profit using the highest bid price and also the highest bid price with enough volume if `DEFAULT_min_orderbook_profit_percentage`

is used.

**The Numbers**

Valid Values: Decimal values

0.5 = 0.5% profit after exchange maximum fees

1 = 1% profit after exchange maximum fees

2.85 = 2.85% profit after exchange maximum fees

**The Formula**

Sell Price >= (average bought price * (1 + sell_value/100) + fees

**Examples**

`DEFAULT_A_sell_value = 1`

→ sell zone begins 1% above the average bought price plus fees. Bid price must be greater than or equal to this value.

`DEFAULT_A_sell_value = -10`

→ sell zone begins 10% below the average bought price plus fees. Bid price must be greater than or equal to this value.

### LOSS

This buy strategy is true when the price of the coin has dropped by the set percentage in the last 24 hours. The percentage is the 24h change specified by your exchange.

**The Numbers**

Valid Values: positive or negative decimal values.

A positive `buy value`

is converted to negative however `buy_value_limit`

needs to be negative. For simplicity use negatives for both.

3 = 3% loss over 24 hours

-3 = 3% loss over 24 hours

-7.5 = 7.5% loss over 24 hours

**The Formula**

Buy Price < (price 24 hours ago) * (1-ABS(buy_value)/100)

**Examples**

`DEFAULT_A_buy_value = -7`

→ buy zone begins 7% below the price from 24 hours ago. Ask price must be less than this value. `DEFAULT_A_buy_value_limit`

must be less than -7 if used.

`DEFAULT_A_buy_value = 7`

→ positive numbers are converted to negative. So result is the same as above.

### SMAGAIN

This buy/sell strategy is true when the current ask/bid price is above (positive `buy/sell_value`

) or below (negative `buy/sell_value`

) the lowest of the two SMA lines specified. It does not matter if the fast or slow SMA line is lower, the bot always looks at the value of the lower line.

If a positive value is used the ask/bid price must be greater than (or equal to (for selling)) the value of the lower SMA band multiplied by (1 + `buy/sell_value`

expressed as a percentage).

If a negative value is used the ask/bid price must be less than (or equal to (for selling)) the value of the lower SMA band multiplied by (1 + `buy/sell_value`

expressed as a percentage).

**The Numbers**

Valid Values: positive or negative decimal values.

1 = 1% of the price above the lowest of the two SMA lines

0 = Right on top of the lowest SMA line.

-0.5 = 0.5% of the price below the lowest of the two SMA lines

**The Parameters**

`SMA_candle_period`

`SMA_fast_length`

`SMA_slow_length`

**The Formula**

Positive `buy/sell_value`

buy price > lowest SMA * (1 + ABS(buy/sell_value/100)) sell price >= lowest SMA * (1 + ABS(buy/sell_value/100))

Negative `buy/sell_value`

buy price < lowest SMA * (1 - ABS(buy/sell_value/100)) sell price <= lowest SMA * (1 - ABS(buy/sell_value/100))

**Examples**

`DEFAULT_A_sell_value = 0.8`

→ sell zone begins 0.8% (of the price) above the lowest SMA line. Bid price must be equal to or greater than this value. `DEFAULT_A_sell_value_limit`

must be greater than 0.8 if used.

`DEFAULT_A_buy_value = 0`

→ buy zone begins on the lowest SMA line. Ask price must be greater than this value. `DEFAULT_A_buy_value_limit`

must be greater than 0 if used.

`DEFAULT_DCA_B_buy_value = -1`

→ buy zone begins 1% (of the price) below the lowest SMA line. Ask price must be less than this value. `DEFAULT_DCA_B_buy_value_limit`

must be less than -1 if used.

→ Use **TradingView** to visualize **SMAGAIN** with this indicator.

If a positive value is used the ask/bid price must be greater than (or equal to (for selling)) the value of the lower EMA band multiplied by (1 + `buy/sell_value`

expressed as a percentage).

If a negative value is used the ask/bid price must be less than (or equal to (for selling)) the value of the lower EMA band multiplied by (1 + `buy/sell_value`

expressed as a percentage).

is used the fast DEMA line must have crossed above the slow DEMA line. If a negative `buy/sell_value`

is used the fast DEMA line must have crossed below the slow DEMA line.

The cross must take place within the number of `cross_candles`

.

If a positive `buy/sell_value`

is used the fast MA line must be above the slow MA line. If a negative `buy/sell_value`

is used the fast MA line must be below the slow MA line.

### PDHIGH

PDHIGH is the previous day high. PDHIGH (though its name suggests a Previous Day) is just a previous **candle**, so you can use it on any supported time period.

This buy strategy is true when spread is higher/lower than the spread between previous candle high and the bid price of a trading pair.

**The Numbers**

Valid Values: positive or negative decimal values.

So previous candle high for ETHBTC was 0.034432

Current bid price is about 0.0321190

So the PDHIGH value is negative (-6.71%).

**The Formula**

PDHIGH uses a spread calculation as follows:

%Spread = ((%Bid Price / %PDHIGH) - 1) * 100

It is this %Spread that we display

**The Parameters**

**Examples**

An example use of this strategy is to buy as soon as the bid price crosses the PDHIGH indicating that a possible break out has occurred. In this case the breakout is to the positive side indicating an upward trend.

DEFAULT_A_buy_strategy = PDHIGH DEFAULT_A_buy_value = 0.00000001 DEFAULT_A_buy_value_limit = 30.0

`DEFAULT_A_buy_value = 0.00000001`

`DEFAULT_A_buy_value_limit`

must be higher than 0.00000001 if used.

`DEFAULT_A_buy_value = -0.00000001`

DEFAULT_A_buy_strategy = PDLOW DEFAULT_A_buy_value = 0.00000001 DEFAULT_A_buy_value_limit = 30.0

`DEFAULT_A_buy_value = 0.00000001`

→ buy zone begins 0.00000001% being positive indicates an upward trend. Bid price must be higher than this value.

`DEFAULT_A_buy_value_limit`

must be higher than 0.00000001 if used.

must be lower than -0.00000001 if used.

### PDCLOSE

PDCLOSE is the previous day close. PDCLOSE (though its name suggests a Previous Day) is just a previous **candle**, so you can use it on any supported time period.

This buy strategy is true when spread is higher/lower than the spread between previous candle close and the bid price of a trading pair.

**The Numbers**

Valid Values: positive or negative decimal values.

So previous candle close for ETHBTC was 0.034432

Current bid price is about 0.0356225

So the PDCLOSE value is positive (3.45%).

### LASTDCABUY

LASTDCABUY is a strategy that buys only if the ASK price is below the last DCA price. This is not the last average price, rather the last price at which a DCA buy was made.

LASTDCABUY does not use an indicator, buy value, or buy value limit.

This buy strategy is true when the current ask price is below the price of our last DCA buy.

**The Numbers**

Valid Values: positive or negative decimal values.

Price of our last DCA buy was 0.0352965

Current ask price is 0.0351170

So the LASTDCABUY value is true.

**The Parameters**

`DEFAULT_DCA_A_Buy_Strategy = LASTDCABUY`

**Examples**

The strategy is true when the current ask price is below the price of our last DCA buy.

**Note:** DCA Buy Value and DCA Buy Value Limit are not used with this strategy.

`DEFAULT_DCA_A_buy_strategy = LASTDCABUY`

### ANDERSON

Anderson-DCA was an idea by a team member (called yea Anderson) that was implemented in the early days of ProfitTrailer. The idea was that you could make DCA buys using different triggers each time to try to get out of a bad position faster instead of using a specific indicator.

These days every strategy uses the same `buy_trigger`

parameters as ANDERSON so there is no benefit (or harm) using it alongside other strategies. However if you don't wish to use any other strategy you can still choose good old ANDERSON.

This DCA only buy strategy is true when the price of a coin has dropped by the specified `buy_trigger`

percentage relative to the average price you have paid for your current holding.

**The Numbers**

Valid Values:
ANDERSON is unique in that it does not use a `buy_value`

, only the `buy_trigger`

that is common to all strategies.

**The Formula**

buy price <= Average Price * (1 - buy_trigger/100)

**Examples**

`DEFAULT_DCA_A_buy_strategy = ANDERSON`

`DEFAULT_DCA_buy_trigger = -3`

`DEFAULT_DCA_buy_trigger_1 = -2`

`DEFAULT_DCA_buy_trigger_2 = -3.5`

`DEFAULT_DCA_buy_trigger_3 = -4`

`DEFAULT_DCA_trailing_buy = 0.2`

In this scenario the DCA level specific triggers will be used for the first three DCA buys. After that, if the bot is allowed to buy more times, the DEFAULT trigger will be used for each level.

In our example the bot buys a coin for whatever price using the strategies defined in pairs_config. Now the bot looks at the lowest ask price in the order book and watches to see if it drops below our `buy_trigger`

. Once the Ask price goes below -2 the bot looks to trail back up by the `trailing_buy`

amount. (See A Traling Story for more info on trailing)

If it successfully trails and is still below the `buy_trigger`

ProfitTrailer tries to buy. After a successful DCA buy the average price is recalculated. and the bot now looks for the ASK price to drop -3.5% from the new average price. And so the process is repeated.

For the 4th buy onwards the default value of -3 will be used indefinitely as no level specific value has been set.

### FIXEDPRICE

FIXEDPRICE is as the name says a fixed price buying/selling strategy

The buy strategy is true when source price is below the specified price in buy_value

The sell strategy is true when source price is above or equal to the specified price in sell_value

**Note:** It is recommended to use this strategy only with PAIR specific overrides as different coins have different prices.

So it's impossible to create a default value to pick all coins in a good price range.

**The Numbers**

Valid Values: positive decimal values.

**The Formula**

**The Parameters**

`FIXEDPRICE_source`

= (ASK,BID or CLOSE)

**Examples**
An example use of this strategy is to buy as soon as the ask price of a pair is below our specified price.

In Indicators Config:

`FIXEDPRICE_source = ASK`

In Pairs Config:

BTT_A_buy_strategy = FIXEDPRICE BTT_A_buy_value = 0.00000016

`DEFAULT_A_buy_value = 0.00000016`

→ buy zone begins when the ask price for BTT is below 16 satoshi.

`DEFAULT_A_buy_value_limit`

must be less than 0.00000016 if used.

### ATRPERCENTAGE

To calculate the Average True Range (ATR), we first need to calculate the true range of each candle period. True Range takes into account the most current period high/low range as well as the previous period close if necessary.

There are three calculation which need to be completed and then compared against each other.

The True Range is the largest of the following:

The Current Period High minus (-) Current Period Low The Absolute Value (abs) of the Current Period High minus (-) The Previous Period Close The Absolute Value (abs) of the Current Period Low minus (-) The Previous Period Close

The ATR is an Exponential Moving Average (default EMA, can be SMA) of the True Range.

**Note:** Due to using absolute values the true range and the Average true range are always positive. It measures only volatility, not direction. You should use other strategies to supplement the ATR strategy.

**The Numbers**

Valid Values: positive decimal values.

**The Formula**

To calculate the true range in any given period:

true range= largest of [(high - low), abs(high - previous close), abs (low - previous close)]

To calculate the ATR plot the EMA or SMA or the true range.

The BSV displayed in ProfitTrailer is the difference between the moving average and the current ATR value expressed as a percentage:

(ATRvalue / MA1value ) * 100

**The Parameters**

`ATRPERCENTAGE_indicator`

= EMA/SMA

`ATRPERCENTAGE_candle_period`

= 3600

`ATRPERCENTAGE_length`

= 14

`ATRPERCENTAGE_offset`

= 0

**Examples**

Buy if the ATR is less than, or no more than 50% above, the moving average. In Pairs Config:

XRP_A_buy_strategy = ATRPERCENTAGE XRP_A_buy_value = 1.5

`DEFAULT_A_buy_value = 1.5`

→ buy zone begins when the calculated percentage is less than 1.5%

`DEFAULT_A_buy_value_limit`

must be less than 1.5 if used.

You can also buy when the volatility is higher than a certain threshold by changing the buy strategy direction.

Buy if the ATR is at least double the moving average. In Pairs Config:

XRP_A_buy_strategy = ATRPERCENTAGE XRP_A_buy_value = 2 DEFAULT_A_buy_strategy_direction = UP

`DEFAULT_A_buy_value = 2`

→ buy zone begins when the calculated percentage is greater than or equal to 2%

`DEFAULT_A_buy_value_limit`

must be more than 2 if used.

### DISABLED

Disabled is used as a buy or sell strategy in place of another named strategy when coin specific strategies are used.

**Example**

`DEFAULT_A_buy_strategy = LOWBB`

`DEFAULT_B_buy_strategy = RSI`

`XXX_B_buy_strategy = DISABLED`

This has the effect of letting you use your default settings except for a specific coin, denoted by the XXX.

The result is that all coins will use the LOWBB and RSI strategies in the example, the coin that is set in place of XXX will use ONLY LOWBB, because the 'B' buy strategy has been disabled.
