Comment on Deciphering NSE's 'Execution Range' circular.

Tanmay,
The exchange came up with the execution range mechanism to handle fat finger trades placed at erroneous prices.
However, the mechanism of revising the execution range is not perfect. It gets updated based on the average prices of trades in the last 1 minute, which if there aren’t any trades, doesn’t get updated. This is the issue you faced on Friday when there was a sudden move.
We’ve tried to explain this in this support article.
