Single Order

Details

• This allows the user to place an order to any exchange via Fyers
• Placing orders needs an app with the Order Placement permission.
• Placing, modifying and cancelling orders together must stay within 10 orders per second. Requests beyond this limit are rejected.
• Every price input (limitPrice, stopPrice, stopLoss, takeProfit) must be a multiple of the symbol tick size, which is available in the symbol master.
• Quantity must be in multiples of 1 for equities, currency and commodity derivatives, and in multiples of the exchange lot size for equity derivatives.
• For a stop order, stopPrice must not be above LTP for a sell or below LTP for a buy. For a stop-limit order it must also be below limitPrice for a buy and above it for a sell.
• orderTag must be 1 to 30 letters or digits, with no spaces or special characters, and cannot be your client ID or Untagged.
• Set isSliceOrder to true to split a quantity above the freeze limit into separate orders, each with its own order id. Allowed only for NSE CM, NFO and BFO, with at most 10 slices per request.
• If the response code is 201, the order request was made but not acknowledged. Check the order book before placing the order again.
• To change or cancel this order, use Modify Single Order or Cancel Single Order.
• For order types, product types, validations and sync vs async behaviour, refer to the Order Placement Guide.
• When order rate limiting is triggered, the API returns 429 Too Many Requests.
• Retry timing is provided through response headers, not in the response body.
• Retry-After — Wait time before retrying, in seconds
• X-Retry-After-Ms — Wait time before retrying, in milliseconds
• Use the retry interval returned in the response headers before sending another order request.
• Rate limits differ between the Standard and Prime plans. See Plans & rate limits.
