Hello @jacharjya1978
We regret that your experience was not upto the mark here. On RMS speeds, we are sure that this execution problem is not on DEXT layer.
Since it is a partner platform where you are facing the issue, we can connect with Algotest team to resolve this and check on the logic where the per hour rate limit for Orders API is being reached (this is first time that we got this). Can you DM me your Client ID and we will take a look on this.
With LPP, the range is defined here: Limit Price Protection (LPP) on Trading in Index Options.
