How can I delete or desconsider the candles (buffers) from previous day?

 

I'm build a EA that I need just candles prices the current day.

I looked for something like that but I could not find.

Could someone help to find that here on documentation?

 
Find the current date. Find the corresponding bar. Don't look before that.
