Has Anyone made An EA to trades the opposite, Inverse or Converse Of another EA ??

Hi there, just wonder if your EA works properly, from what i do understand it will open opposite trade with lot value u set, so u end up with two trades one original lets say LONG 0.01 lot and other SHORT 0.1, for some reason it doesn't behave this way, actually if i do set magic no for that ea and fill in magic of EA i want to copy i doesn't do anything, if i type magic opposite way it will close immediately whatever will be opened, i would be very great full if u could review that... or maybe i am just completely wrong.

Also if u don't mind: i do attach some ea here, would you like have a look at this ea and remove from its code risk management, and implement for instead such logic: it has to recognise last trade and establish whether it was win or loss, if win standard lot setted will apply if loss occur id like to have possibility of setting lot value till win occur,

i do understand that u must be extremely busy so there is no problem of me re compensating Ur afford, as long as i can afford You.

I no there is plenty programmers out there but knowing ur input to this website, cant think of any one better. Thank You /plz excuse my english/

Is anyone here using an EA (Expert Advisor) for gold (XAUUSD) trading?

Yes to Both questions. Do you currently trade Manually? are you intending to automate this strategy? If you are able to write out your trading rules in a recipe format and objectively describe your objective for said strategy in under a page:

then Do So the copy that into your Favourite AI Agentic helper. you would be suprised to see what will result. if it is that you choose to ask that said automation be done for Mt4.0, there are several threads here with persons that chan help to commercial pro your resulting EA.

Hope that helps for what you intended.

Interesting idea, but there's a common trap here worth flagging.
An EA that went from 60% to 10% didn't necessarily become a reliable contrarian signal. It most likely went from trading in favorable conditions to trading in unfavorable ones — and the signals may now be random, not consistently wrong.
For a "flip" to work, the EA would need to be consistently wrong — not just unprofitable. An EA with a 10% win rate and tight stops could still be losing due to poor risk/reward rather than bad direction. Flipping the entries doesn't fix that.
What tends to happen in practice: the flipped version performs well briefly, then also degrades — because the underlying market regime shifted, not because the original logic became a reliable counter-signal.
A more productive angle might be regime detection — identifying when conditions suit the EA and only running it then. That's a harder problem but a more durable one.
That said, the core idea of monitoring EA performance and adapting behavior based on recent results is sound. Just be cautious about assuming "wrong" is the same as "consistently wrong in a useful way."
