Subject: Upstox Modify Order V3 – SL-L to MARKET Conversion, Partial Fills and Order-State Confirmation

Hello Upstox Developer Team, We are finalizing the design of a safety-critical intraday NIFTY options trading system. Our system places a protective SELL Stop Loss Limit (SL-L) order after a confirmed BUY fill. At a defined profit target or mandatory intraday exit cutoff, we intend to modify the SAME existing protective SELL order from SL-L to MARKET using Modify Order V3, without placing a separate SELL order.
