Request for Market Protection (MPP) Details and API Enhancement

APIs, Automation, Algos & Code

Hello @Dhan @PravinJ @Hardik

Hope you are doing well.

I wanted to understand how market orders placed via Dhan API are handled in terms of price protection. Specifically, could you please clarify:

  1. What is the default percentage of market protection (MPP) applied across different instruments (attached snap is of Upstox reference for you)

  2. Is there any internal mechanism similar to Market Price Protection (MPP) used to prevent excessive slippage?

Currently, I could not find clear documentation regarding this in Dhan’s API.

For reference, brokers like Upstox provide detailed control over this feature. They allow users to:

  • Use a default protection (-1) based on exchange guidelines

  • Pass a custom protection percentage (1–25%) in the API request

  • Restrict orders without protection (0 is not allowed)

Additionally, they expose this directly in their order placement payload, enabling better control for automated trading strategies.

Example (Upstox API structure):

{
  "quantity": 4000,
  "product": "D",
  "validity": "DAY",
  "price": 0,
  "instrument_token": "NSE_FO|43919",
  "order_type": "MARKET",
  "transaction_type": "BUY",
  "disclosed_quantity": 0,
  "trigger_price": 0,
  "is_amo": false,
  "slice": true,
  "market_protection": 1
}

This flexibility is extremely useful, where controlling slippage is critical for performance.

It would be very helpful if you could:

  • Share how Dhan currently handles market order protection

  • Consider enabling a similar customizable market protection parameter in the API

Looking forward to your clarification.

Thanks & Regards,
