if i do a test of my new EA and it says it has a profit ratio or w.e of .80 is my EA crap?

because before i prorammed the EA i was visually foreward testing it for a long period of time and had huge gains, even when i built in big buffers for slippage & etc.

You should really check out the search function, what it does is quite magical, it finds other posts based on key words that you enter, this allows you to find out in advance if a subject has already been flogged to f**kin death before you add your own useless bookend to the pile of endless subjection.

ok. here is the specific example i am talking about.

over the last two months this system has had big profits for me, now i made it into an EA which would have made it more profitable for me, over that same time period according to my own calculations.

but i just tested the same EA (still got some kinks to iron out though in the programming) and this is the result i got from 1971 to now, with the "Model" as "Every tick" on the EURUSD 30min.

should i throw up this EA? no right?


oh, but i just realized only 500ish trades were made, so it coudlnt have tested it from 1971 to now, because on average there is 2 trades a day



p.s.

I once knew this guy named Craig who was huffing gasoline while smoking ( no joke) and lit himself on fire by accident and had 3rd degree burns all over his face and hands.

forward testing is more reliable than backtesting. If you have at least 90% modeling quality, maybe that'll be true in forward testing. It depends. Try forward testing.
just my 2 cents.
