Dear experienced traders,
How do you think for a sustainable EA, how much win% should be needed at least?
Other points such as profit is more important than win%, but win% is still an important question to design strategies.
Over optimization is horrible, even that we have to keep win% at least.
If you are using many kinds of strategies, you can choose more than 2 choice.
Thank you in advance and best regards
What is the point of this poll?
There is no right answer as it all depends on the Risk:Reward ratio.

Thank you, Keith.
I'm having some study about some strategies, some of them are very special.
I'm not sure there is a right answer or there is not a right answer, but we have to find a reasonable answer...
A classic mistake is to focus solely on win.
You can also try to focus on limiting loss.
For example, when i set my max loss for my next trade to -$100 then i will not know any win yet, but i do know that i will not lose more then $100 on my next trade.
So i have successfully 'predicted the future' in terms of the worst case scenario without ever focusing on win.
The last Basel implementations that I have seen had 5 statistical groups/levels of risk
1 group => loss from 0% to 5% <= acceptable the best
2 group => loss from 5% to 20% <= acceptable
3 group => loss from 20% to 50% <= not acceptable but continued
4 group => loss from 50% to 100% <= not acceptable need to terminate
5 group => loss more than 100% <= not acceptable extremely badThe last Basel implementations that I have seen had 5 statistical groups/levels of risk

80% looks very over optimized.
May I ask how long will be your back test for?
For example: 1 year, 5 year...
For a sustainable EA, how long period back test should be needed at least? (with 99% high quality back test data)- 2020.12.28

Thank you so much, Marco.
I got it.
Usually EA opens a lot of trades. In fact, too many. I would surmise a high win rate is needed to be profitable. Of course R:R matters more, but a great R:R ratio is not always possible in reality.
Thank you, Koh.
Yes, it depends on the strategies, scalp have to win a lot and trend do not need the have a high win%.
