Greetings Support.

For about few month in order to speed up my backtesting I tried to improve it by Cubic Spline Interpolation method. I found that it gives me different indicators value, and therefore as a result of different candle OHLC prices.
See a picture.

By a red circles I shown only that I firstly got in my sight. So difference on any candles.

Please investigate.

Higher highs and lower lows are possible in Cubic spline. Avoid this method if this is important.

What that means? Do you plan correct this issue?
That is a only one method to speed up a backtest on Jforex platform keeping a maximum simulation of market action.

I mean this is absolutely normal with Cubic spline method:

There is another one method available, which is "4 ticks at OHLC". It does not have this problem.
