How to get historical data of say last "n" 5 minutes candles ? What FROM DATE should put ??

Mangesh

if i want to get historical data of say last 20 candles of M5 then what "from Date" should I put ?...

If I call the function at say 2.45 PM then it has 20 candles for today...

BUT, If I call the function at say 9.45 AM then it has only 6 M5 candles for that day and other 14 candles should be from yesterday closing...

This will vary all the time with different current times and current date etc..
