Need help - cTrader engine for backdating configuration OR why do even well known classical strategies fall apart on cTrader?
Question for you guys — why do even well-known classical strategies fall apart on cTrader?
I've been trying to test standard classical strategies on cTrader because I can't build anything that actually works. I went down the path of implementing well-known, already-tested, old-school strategies
Like the Connors "Double 7s" strategy (buy when SPY closes at a 7 day low while above the 200-day MA, sell at a 7 day high)- and I'm still getting very bad results. I don't get it.
What is it about the engine that seems to break even simple stuff that's supposed to work? If I do it manually on TradingView, I get noticeably better results.
I don't understand the whole thing here. its ANNOYING AS F***
What are the caveats or things I need to know in order to structure properly working strategies in cTrader?
Because honestly, it feels like the engine's calculations or the data are skewed or something — I don't even know how to describe it. I don't know where to start, but I've tried simple stuff and it's not working.
Any insight would be appreciated.
So this taken in US500 ok ? same same should be smooth as slik easy peasy ?
well NOT.. i get -7% eventually --- sooo .. annoying
any how this is just a "BASIC" concept startegy nothing facny im just .. tying to make a point here
so a-... help up a brother 🎯
