This is where risk management comes into play. You should know going into live trading what your worst case scenario is and trade accordingly. If your strategy has a 20% win rate and you risk 10% of your capital on each trade then you're a fool, and will be a broke fool very quickly. However, a 20% win rate will absolutely work if your winners are outsized and you risk say 1% of your capital.
"Profitable" and "robust" have nothing to do with win rate. You have a lot to learn...
What's the point of trading then when you can't even risk 10% of your capital on a trade? LOL If you have $10K, you are telling me you can't even risk $1K on a trade just because it will lose 80% of the time??!! LOL If you are going to lose 80%, WHY bother trading??!! LOL Just to lose? By the eighth time, even if you risk less than 10% of the capital, you would've lost all or significant amount of capital that you won't have much left to trade even if the next one could be your home-run winner. And if you are only risking so little of your capital to trade on each trade, even if you make 100% of what you trade, your overall return would be very low. I said, I understand win rate isn't everything but when it's too low, it's really not worth it to trade.
But anyway, to each's own taste. If a 80% loss rate works out for you then that's fine with us.
