Ladies and gentlemen, I am relying on you!

Please advise conceptually how to handle the bars from 15 to 15.55 for the last 250 trading sessions. I'm a bit confused by the amount of information...

Filter Saturdays and Sundays usingMqlDateTime

Aleks,

use an indicator with the function

OnCalculate(const int rates_total,

const int prev_calculated,

const datetime &time[],

const double &open[],

const double &high[],

const double &low[],

const double &close[],

const long &tick_volume[],

const long &volume[],

const int &spread[])

{

to access all history bars?

Guys, where can I read about weekend and holiday filtering?

I only need the trading days of the Asian session.

Are they on the chart?

[Stairway_2_7]

pako,

const uint SecsPerDay = 60 * 60 * 24; // number of seconds in a day

datetime newtime = TimeCurrent() - SecsPerDay * 6; // calculation

Alert(newtime); // output result

I can find the last date like this. The answer is March 19, Saturday. And I only need weekdays.

You got me wrong,

There are no Saturdays and Sundays on the D1 chart.

Why look for something that doesn't exist?
