Drawdowns come. Scalping, day trading, swing trading, and investing. Just ask Buffet about his Dexter shoe trade. Or Victor Niederhoffer who lost it all two times I believe. Or if you could ask Livermore who went broke 4 times I think it was. Investing, nor algo trading, nor scalping, are immune to drawdowns. Neither are large accounts or small accounts. I understand about 1/2 of hedge funds fail. But to try and answer your question:
If I suffer 3 or 4 trade losses in a row (which is rare for me) I will go directly to sim trading. Why? For some reason I am not in sync with the markets or PA. IT could be my mental or emotional state at the moment. Why throw good money after bad? If I can't get it straightened out on a SIM I likely will do worse with real money. I believe a scalper has to maintain a high win rate. He also has to take his losses when his premise for taking the scalp is no longer valid.
In particular if I make a losing trade my mental goal is to recuperate that loss, and some, over the next two trades. The way I do this is by selecting a new trade, then doubling up or tripling up my position size, and then going in the market direction that first handed me the loss. If, I think, there is movement in that direction, that yet to come. If not, then I will wait for another trade in either direction. That basically means if I am right, then in 1/3 to 1/2 of the movement distance (that caused the loss for me) I will be back at BE and likely more. This is not for myself revenge trading, rather it is a process that I follow to get back my loss. Some would call it revenge trading but it is not an emotional decision for me, but a logical decision based upon a calculation. That being that I will likely get the movement I need to get me back into profit or at least at BE. If I get whipsawed out on my doubled up position I will resort back to SIM again.
Then I will give it another shot doubled or tripled up. If it works I will likely repeat it again. That will usually get me back. If on the second try I get whipsawed again I will likely quit for the day and go do something else. My brain just is not working correctly. I am making wrong judgements.
I had a case today. It may make the concepts clearer. I was ahead with profit bagged. We got a little sideways movement on the 5m MES chart. I decided to short about the middle of it. First red triangle on the left. Then I added more (second red triangle above it) Then I added a third time (red triangle on the next bar. Guess what? Price kept going up. We now had 3 consecutive bull bars. On the 4th bar I decided I am wrong so I dumped the entire position (first green triangle left to right). It kept going up so on the next bar I decided I needed to double up and get back my loss. That would be the second green triangle from left to right. I exit that double up position on the next bar (red triangle). Then I went long again just above that exit (doubled up again) and then exited that second doubled up position on that upper red triangle on the next bar and final bar that shows exits and entries. Finally, on that same last bar as price dropped some I went long again but at my original size I had when lost, some bars back. I then exited that same size on the same bar at the lower red triangle on the last bar on my chart that has entries and exits.
In essence, to get back my loss and back into profit, I double up my losing position size TWICE and took a third trade at the same losing position size. So, three winners in a row and by the time the dust settled I not only got back my loss but made a handsome profit. All this over six 5m bars.
That is how I get back losses. It is not easy to do psychologically but I look at it as a process with executions that will get me back from what a lapse in judgement cost me, or just what the market just simply threw at me. I cannot focus on the money. I have to focus on the process and execution.
That gets me out of the scenario you describe of needing to get 8 wins to get out of the hole.
I have explained this process before in my journal. You may want to review.
BTY even after my loss I was still holding a profit from my earlier trades on the day, when I started the recuperating trades.
