Historical Data Replay different from real market data

[eddieTraderr81]

Hi,

While testing some trading strategies, I have downloaded the market data for a day and, when I replay the data using the ticks chart, I have observed that the charts (candlestick bars) are slightly different than they were in the real market session, (since I can compare with the video recording from the live market session for that day).

That has some impact on my trading since some candles are different during replay than they were during the real session, they have different shape, different body.

Is it any way to fix that or mitigate it?

Thanks.

• Select Adjust date/time
• For Windows 10 click 'Date, Time, and regional formatting' -> Then click 'Additional date, time, and regional settings' -> then click 'Set the time and date'
• Select the 'Internet Time' tab at the top
• Set the server to time.nist.gov and then click Update.
