@Moderator_1 : For NSE equity I can query 15 min candle since 2016-10-03(3rd October, 2016) and not before that.
By intra-day you mean, 5 min , 15 min candle . correct ????
If yes, the limits are quite close to what you stated above (I tested on NIFTY and tata motors(equity).
By interday you mean, 1 Day candle since 1990-01-01 can queried from API?
It is super-important for my algo trading strategy at 15min, 5 min candle for at least for last 10 years. Can you provide such API ?
