Has anyone ever had an issue where you would run a back test, get results. Then later, run the exact same back test, same dates/times/parameters and get completely different results? I can understand them being a little off, but I’m talking about one time making $800+ TP in a day then run it again later and it loses over -$300. I don’t get it-the data and parameters are the same but its not consistent.
I also tried this again using a fresh install and fresh VPS, same issue. I was testing Renko type candles, could that be the issue? Thanks.
It’s because of derivative types like Renko. Try to look at the same time after a few reloads. You’ll notice that sometimes the candles don’t form exactly the same. This cascades and now your strategy is off because the candles aren’t formed exactly the same each run.
That may also be why I’m told market replay on those types of candles may be inaccurate overall as well. Normal charts and candles it seems are more consistent test to test and with Live.
Thanks for the response. It seems now I’ve been wasting a lot of time back testing lately.
