How to buy something when the price crosses a particular value

@Streak Let’s say today’s market opened at 50Rs (opening range, 15 mins, Open).

I want to buy exactly when the price crosses 50Rs.

Buy = high(0) crosses up (opening range, 15 mins, Open)

If I give like this then streak waits for the 15 min candle to get over first and then tries to buy. I don’t want that. I want to buy the moment the price is crossing that value. Not after the candle is finished. How can I do that?

Set the timeframe as 1min to get alerts quickly. It will check for 1min candle to close before sending a trigger. You cannot execute on the basis of LTP in Streak.
