Basically, the last few months NASDAQ 100 never got 3 ticks without a minor DD, followed by the bottom confirmation. (2x) So, everytime it goes against you, close it and wait for the confirmation, once it's up buy back and watch it fly. You'd save some few important percentages doing that, all it takes it's active control of your positions, even in the long run.
I buy a few coins every couple weeks to accumulate to a long-term buy and hold position. Instead of just hitting the buy button I set up limit orders at potential bottoms. This typically saves me $10-20 regardless of direction. My next buy will be in 300-340 area
