65% win rate

I was wondering - how about increasing lotsize after each LOSING trade? I know, it is a bit martingale, but if you're having consistent 65% then ROI-wise it will bring best results.

If you really have 55% WR with 1:2 RR, then you can try this approach: https://www.forexfactory.com/showthread.php?t=444377

How this is relevant to my question?

Actually it looks interesting enough and these statistics can be really strong. But the most important thing is that it can be put into practice. Because if you manage to do it only once, it is too early to talk about some dynamics and development, and if you manage to do it all the time - at least for 3-4 months. Otherwise you can't do it. And I would also like to know in more detail about the assets on which this approach can be applied, and with what situations this approach does not work, the lead is necessarily a situation in which you miss the entry point. In general, it is great when a trader reaches the stage where smb can create strategies.

How do you know you have a 65% win rate? Backtesting? Forward test on demo? This matters. And also how long have you traded this strategy.
