Set the maximum number of pairs that the bot is allowed to have at a certain DCA level.
ie, you can define I want to only have 3 COINS at DCA level 1 and only 1 coin at DCA level 2.
This means that if you currently own 2 coins and 1 of them is at level 2, the other one will have to wait until the coin at level 2 sells before it can DCA to level 2
DCA_level1_max_trading_pairs = 3
DCA_level2_max_trading_pairs = 1
