However, please note that EA Studio creates the best experts for the given market data and settings. The reversed signals may not achieve similar performance.
I totally agree. I've written long ago about the reverse trading.
In a simplistic terms, we think that a bad EA is due to wrong direction. However, upon closer examination, it's far more complicated why an EA isn't making money.
1. Wrong direction (simplistic view)
2. Correction direction but late exit
3. Correction direction but premature exit (low reward/drawdown ratio)
So even if you reverse a bad EA, you don't turn a bad EA into a good EA. Because a good Ea comprised of both good opening rules and closing rules. Reversing the opening direction doesn't reverse the closing rules because bad EA usually exit because of hitting SL or tight SL or premature exit.
I won't want to waste time "harvesting" bad EA and hoping reverse trade will make it profitable. Even if it's profitable, I don't think it's performance metrics such as profit factor etc would be outstanding.
Nevertheless, out of curiosity, we sometimes still want to try despite being told not too. I tried and thus I speak.
