ON apparently does the larger moves such as you describe. You are talking about in larger moves. Rarely do I do 50 pt moves. However, There is some truth to what you are saying. If I am going for a measured move swing trade (2 or more legs is how I define intraday Mm) say on a BO and then averaging in on PB’s i.e. I am doing what I consider an intraday swing instead of just a straight scalp then the senario changes abit. I will be going for bigger profits. And not trying to BE on first entry and make money on subsequent profits from the averaging in positions. In intraday swings I am going for profit on ALL entries, initial and subsequent averaged down entries. And I know I will likely be in the market for many more minutes or even hours than when straight scalping.
In addition, I make an initial SL tied to my original entry as a best guess based on my assessment of immediate PA. However, that is usually supplanted by an actual SL. That is, how far the market actually moved against me, in reality, and not my initial SL. Therefore, in the final analysis my RR ratio is based on my actual SL or adverse movement. So, when the market doesn’t come close to my initial SL then turns in my favor with all my averaged in positions my RR changes for the better because in actuality I never had to risk the entire initial risk. I only care about actuality in math in terms of the metrics of the trade.
If it doesn’t turn in my favor sufficient for exiting and actually hits my initial SL then yes I take a bigger hit and I recuperate that by doubling or tripling up in the new direction. When I am wrong then..I am wrong ..and when my original assessment of PA and and my entries and exits based upon that assessment are faulty then I have to accept that and mitigate the losses and try to recuperate them. No point in holding on and hoping. The market has proved me to be wrong.
If I am in a trade anticipating a MM and it doesn’t happen after I loaded up then I will simply take whatever, the market gives me.
