Does anyone know how valid the data for backtest on a closing price basis are?
Background: I don’t trust the SL of say 1% within the tick-by-tick data. Therefore I work on a closing price basis or on the data of Open, High, Low, Close of the respective 4H-candle.
So I wanted to ask how reliable are the data of the Open, High, Low, Close of the 4H candles and how far back do the data reach in their reliable form?

OHLC data that you have on your charts are the real OHLC data obviously 🙂
Fine. 100,000 units is good, no problem, I can work with that. More than 100,000 units back but not?
Don’t be so sure about the correctness of the OHLC data. Look in my thread “ATR miscalculating”. There are definitely differences between IG’s OHLC and PRT’s. So I’m not sure if your backtests will reflect reality.
