I've always found it easier to just take the first loss and go with the flow of the market myself. I will occasionally "pull" or, rather "pause" a stop loss to make sure T&S is, in a sense, confirming the adverse move. But I will stop out rather than average a loser, everytime. Too much to make by just going with the flow, which means there is too much to lose by fighting it. I guess it works for some. But it would cause me no end of stress until I pulled the plug on the trade one way or the other.
I use cycles and I know I will be early most of the time, so averaging down has back tested 15 years to show me it works extremely well especially on breakeven plus one tick trades. I either never understood the feelings of fear or understood loss of money, I respect the markets, but I either mis-understood value of money long ago or never understood it. For the longest time, 98% of funds I trade for myself been in 401k LLC, and kept alive from working for our government three times, real estate rentals to the government, eight businesses I started and sold off and truck driving. I think when you can take the stresses off oneself, allows inner self not to get stressed out. But having other entities to keep busy has also mellowed out a little of the tension to not get frustrated when a loss happens, but I strive for as close to zero losses and in long term I strive for positive expectancy, which I have discovered can happen in stock markets. But have gone to automation now as memory is weaker now, plus I never actually enjoyed the manual part of trading and nor does my biz partner, so we both different problems associated to the unknown. I just have problems of being wrong, has nothing to do with the loss of money, and after 40 years of these feelings, doubt they ever go away. But automation I seldom even watch the markets, it trades 24/5.5 and around the world, nothing could be finer.
The recent system I have recently built is both scalper/day trading, it has nailed 35 point moves with up to several added on signals going with the trend, but when in controlled chop, it reverses constantly, so like in a 20 point range for the day, based on 2 lot, system averages more than twice the range but can be up to 65 trades, and very few losses. Taken me forever to have this method as I have turmoil within myself of frustration levels when I have losses, I do take them as flaws and start looking for patterns on how to get rid, but everyone has their own parts of themselves they try to change to get better.
