What's an honest monthly return to expect from automated trading?

Every “+50% a month” claim you see is either a martingale about to blow up or a backtest cherry-picked from a bull run.

Sustainable automated strategies live in single-digit annual percentages with controlled drawdown far more often than people want to hear — and even good ones go through long flat or losing stretches. The compounding math that looks magical over ten years assumes you survive every drawdown in between, which is exactly where over-leveraged accounts die.

I’d rather have a boring, survivable edge than a thrilling one that ruins the account in month three. What return expectation do you actually run with, and has it changed since you started?
