I need to rethink the target. I found that mainstream coins (top 15 by Market Cap) used for Martin have too little volatility and are prone to clear swing trading trends. It is not easy for Martin to take profit, and it is also easy to experience a continuous decline with weak rebound. Even if small coins fall, they are more likely to experience significant rebounds, providing opportunities for Martin to take profit.

I now have a bit of an idea to change to using the hourly K line for the past three days, a total of 72 K lines, excluding one or two with significant fluctuations, sorting the targets with significant fluctuations, and at the same time meeting the trend of non-short positions (which is currently very subjective), like CAT, which has a large volatility, even Long Wick Candle is prone to Rebound take profit. It's a pity that this stock does not support trailing stop orders.
