Make sure you dont cut losses straight out of that gate as soon as the stock doesnt go your way. Sometimes they have tendencies to bounce back, so make sure youre not pulling the trigger too quick when you sell. Try to start with only a few trades a week and make sure you really do your research. Typically the best times to are premarket/post market or beginning of the day.

I am a total noob trader and I only trade on average1-3day cycle. What are you using for strategy? From your trades the "Cut losses quickly" mantra may be destroying you. I personally rarely cut losses because I buy stuff on sale and then I buy it MORE onsale.(my main strat). There is a volitility in price and I think your stops or cutting is too tight to take into account this "rubberbanding" as I lkie to call it.
