If some or all of your TPSL lines are not placing, one thing to make sure is that the amount you are trading is high enough to support having multiple lines that take percentages of that amount.

For example if you are trading $10 on a coin whose minimum buy is $10
you will not be able to set a TP to take 50% of that position. Because the minimum order is $10. If you made your leverage x2 in that example, it would work, in theory.
