Issue with first bars of new trading week

New comment
 

My python algo script sometimes returns incorrect bars at the start of a new trading week, wiht the most recent bar.

I call copy_rates_from_pos twice, with a 30s delay.

I have max bars in chart set to the lowest, 50000.

AI tells me that it could be an issue with the caching, and I should

a) set max bars in chart to unlimited

b) use copy_rates_range instead, as it is more stable


Does anyone have any experience with this issue?

Thanks!

Post the code if you need coding help.

It's advisable to check if the terminal is connected (could be not yet connected at start-up or after a connection drop off), and timeseries are synchronized - before calling copy rates.
