Thanks John, but I already used delete all data and download from the edit menu... ...and then deleted all the price data files from the Data folder, reloading it all again... ...and just in case, I have also now done it like you suggested too... The errors remain, exactly the same error at the same points... - the first two hourly candles on NFLX 1st Sep 2020 show no Low value. Same on the 12:30 (4th candle) too. Same problem on two separate computers too. So I looked into this more and applied a simple search across 60min candle data (freshly downloaded Sierra Chart Historical Data)... I searched SQ, NFLX, ZM, MA, ROKU, TSLA, MSFT, AMZN, AAPL, AMD - each for all data for 2020. I found 21 OHLC data entries that were ZERO. - these are PriceData errors that are potentially problematic! - they will trigger erroneous Algo trades. Even if they are only historical data errors (I wouldn't know for sure)... ...but they are still going to give errors in backtests. I guess the origin here is data errors rather than a bug as such, but still a problem... Can someone look into it and ask your data sources to fix it for the future? I checked similar data (the NFLX examples as above) on TradingView and price data is fine there. |
