Congrats on your success, patience and under trading is a virtue. Many simple don't trade on Fridays as they find it hardest day to trade, are usually tired from the stresses of trading, I use to have a rule that if I was up on close of Thursday for the week, no trading on Friday. I did that for handful of years long ago till I honed my skills. Also, I have kept good stats of my trading, I know by the hour and by the day that if I go past certain number of trades, I make matters worse. I believe there are cycles and my methods work most of the time, but when they don't work cause of this cycling, I will grind it out till I make enough to cover fees and quit for the day. Now most of what I have is automation, but have developed a couple systems, so testing them out after I done enough back testing to know they should continue to work forward, have best buddy programming them, I don't seem to have the skills any more or patience to code, another thing in life you lose if you don't keep doing it, LOL.
I never even think about money on the table, I like to think positive and what I don't get is negative so why think about the coulda's-either make it better, coming out profitable on the week is super. Cause for most part am a scalper, so I have small targets and reach a goal, no matter what time it is, am done on the day, so it has become more of a job to get it done, then back test something else.
Have you done MAE and MFE back tests, they can help on risk and targets, if trading 2-3, take off 65% off at target and have a runner. I base this on your results of bigger losses than profitable days. Midcap is sort of like Russell or crude oil, runs hard one way then runs other way hard, most of it fits BB20, 2 going from one side to other in chop. It is a market I have traded a great deal manually and now automated. Once in a blue moon get 5-600 move on day trading methods, but scalping is nice as well as getting a buck, just can't do volume, even a ten lot can hurt, really hurt $100 plus per on the getting out. It is a market you learn how to use stop limits, LOL.
