Frequently Asked Questions
What does MPP stand for?
MPP stands for Market Price Protection. It's a safety feature for your market orders.
What is the main goal of MPP?
To prevent slippage (buying too high or selling too low) in fast-moving or illiquid contracts, especially options.
Which type of order does MPP protect?
Market Orders (Buy and Sell). It automatically converts them to Limit Orders for Option contracts.
How does MPP work?
It calculates a defined percentage buffer around the current price and turns your Market Order into a Limit Order at that buffer price.
What happens if the price moves too far?
Your order will be unexecuted or partially executed, and the remaining quantity will stay pending as a Limit Order.
Can I turn MPP off?
No, it is a mandatory, broker + exchange-enforced risk control measure.
How is MPP calculated?
Default MPP percentages for Option contracts:
Index Options = 10% of LTP or 20 Rupees Minimum absolute value
Stock Options = 20% of LTP or 5 Rupees Minimum absolute value
Example of MPP in different price movement scenarios
An index option contract trading at LTP 300, if a buy market order is placed for 1000 quantity by a user it will be converted into a Limit order with a maximum buffer (MPP) of 330.
Scenario 1: Next available bid is below 330 with quantity more than 1000
Result: Order will be fully executed at best available price.
Scenario 2: Next available bid is beyond 330 with quantity more than 1000
Result: Order will be pending (which the user can modify later)
Scenario 3: Next available bid is at 330 with quantity of 500
Result: Order will be partially executed for 500 quantity and remaining 500 quantity will be pending.
