I agree that a system with under 10% win rate has zero edge and is not worth trading since not only are you losing money on trades, but you are losing money on commissions making the hurdle to high.
The % of a good trend following system should at least reflect the % of time a market is trending. The market trends more than 10% of the time so instead of trend following, you are looking for some super trend if your win % is lower than 10%.
Also, in the real world, a 90% win rate system has a 90% chance of ruin. The reason being most 90% win rate systems stops are the amount of money in the account.
This is of course different if you have an actual edge for example, you are a large Hedge fund with co-located servers that pays for a 1 second look at incoming orders and can then legally front run them so that even a 1 cent movement produces profit due to large volume discount on order flow.
