Well you are also dealing with the fear of trading live. You are killing your winners quickly since once you are in the money, it is too painful for you to see if they are going to turn against you and head back to your stop.
If you want to average into a trade, I would suggest still having a stop even a wide stop, plus use your natural target that you were planning for the trade.
If you want to average in, know that you plan to do this before you enter the trade, trade a small qty and decide how far you are going average into the trade.
For example, you plan to max trade 900 shares, and plan to average down 2 times, you could put in 300 shares each time, knowing that the market can still trend hard, and one day you will take a big loss, but that you are ok with this since your win% is 80 to 90%.
Obviously, chasing a trade is bad, if you get in a trade at the wrong price, then it is too far away from your natural stop, and also can no longer pay you the profit to justify the risk.
Normally, I rather just take my profit or stop targets knowing that I got in best that I could based on my signal.
However, one time last week, I did average in once since I saw the natural stop was near plus I got another good signal and was watching the market while I was in my trade. If you average in, it should be based on some type of logical reason for entering in again for example you get another signal whatever rather than just averaging down and hoping that the market will go back up to your target. I took 1.75 profit when I should have taking 2 points in the es, so even I have this problem of not holding till target sometimes.
I think you need to decide what way you want to trade, either picking good spots to get into the trade and having the strength to hold till it reaches your profit target (if need be step away from the computer or trade smaller size to prevent emotional thinking) plus not chasing if you miss the entry, or averaging into a trade with a wide stop.
To prevent revenge trading, how about having the strength to just sim trade one style or the other on Tuesday, your choice, no real money. Then on Wed, trade the same way you did on Tue if it was profitable with real money but small qty. On Wed, do NOT use sim. Sim is only for testing out ideas, most traders stop using it once trading real money unless they have a new idea.
Obviously, if trading were easy, everyone would do it. There is no way to win every day, the goal is to make money over time. To decrease draw down, you need to let winners hit targets and not chase, and not revenge trade plus only take good signals with multiple confirmations.
