So I ran a few backtests of my algo on tradingview last night and I decided that I *really * don't like their backtest engine.

First the summary.
Typically 32% - 48% of the trades made money. The average was ~35%. The typical gain on the trades was 35% and the profit ratio varied between 1.3 - 1.9, typically ~1.6. Which is very high. As a result the gains were big. Drawdowns were ~5% to 9%. I can live with that.

Having stoploss was a very bad idea. Having profit targets arguably improved the results. The most defining factor was the timeframe (not a surprise to me).

But I don't trust their testing. They run weird things in the background and try to pyramid the trades. They also try to estimate what the fill price would have been. I don't want any of that. All I want is stats on trades if I bought at the price I tell them and reversed positions at the price I give them. I can program for the slippage and fill estimate on my own.

Simple as my ask is, they can't do it out of the box and I have to write it myself :(
