Market Price Protection (MPP) converts market orders to limit orders based on a predefined buffer to protect users from unexpected price fluctuations. This is applied for illiquid contracts.

For eg. If LTP is 100 for an illiquid contract which you are buying at market, we send a limit order of 100+2 i.e. 102.

The buffer value is determined by the segment and LTP as follows:

Segment	LTP (INR)	Buffer
Stocks, ETFs and Futures	Less than or equal to 100	2% of LTP
Stocks, ETFs and Futures	Greater than 100 and Less than or equal to 1000	1% of LTP
Stocks, ETFs and Futures	Greater than 1000	0.5% of LTP
Options	Less than or equal to 500	₹5
Options	Greater than 500 and Less than or equal to 1000	₹10
Options	Greater than 1000	1% of LTP
