How to get an Open price at specific time?

Hello, I need help on getting the opening price at specific time in the past (e.g. Open_price =Open("USDCHF",D'2008.9.1 12:00'),", ",

I don't think there is a way to do this natively. You might be able to do it with something like iOpen but that only gives you a certain number of bars and it sounds like you want to go back further than that.

The only way I can think of is to create a database with historical prices and then write a DLL that has the function in the way you want wrote and that would access it. Another way would be to load the data in a CSV and then just access it from the file functions within MQL. That would bypass the need for a DLL but require a large-ish CSV file depending on how much data you want and how far back.

depends on the time, but it's possible to get it on the minute, only if the bar is in your active chart history.

so...

double Open_Price = iOpen(NULL, PERIOD_M1, iBarShift(NULL, PERIOD_M1, {put date here}, True));

Thank you Ronald Raygun. I follow your example and I am able to get the open price of any date-time that I want.

Wish you the best.
