that win rate is too high and should have raised a red flag and it is what was waiting for the system - the tail event
I posted about this a few weeks ago as a reply - Can you make over 50% per year with < 40% winners and 1.3 profit factor? - #3 by QFund
when you see such high win ratio (anything above 90%), just look at the trading record and look for the trade which shows very high drawdowns. See if there is significant increase on position for those trades. If those trades ended up to be green or breakeven or even a very small loss, expect trouble in the future.
here’s a link to which you were also contributing - it speaks about what might be going on behind the scenes when you have unusal high win ratio - Follower guide to consistent profits
having said that, there is still a chance you will see a spike in the mentioned system’s equity curve going back all the way to new high in a day when market turns in favour of the system. ( I have seen that with another very popular system in recent days) But of course, at some point in future it will happen again until adding to losers is not a option due to limited capital.
