Broker server throws this error when it receives an invalid order. Some of the common causes are:
- Incorrect stock/derivative symbol being passed
- Invalid quantity: Quantity not in multiples of derivative lot size
- Example, lot size for NIFTY is 75, so to buy two lots of NIFTY future, you must enter 150.
- Invalid disclosed quantity
- Disclosed quantity is higher than quantity
- NSE/BSE (Equity) = Disclosed quantity cannot be less than 10% of your order
- NSE (CDS) = Disclosed quantity cannot be less than 10% of your order.
- NSE/BSE (F&O) = There is no disclosed quantity option
- MCX (Commodity) = Disclosed quantity cannot be less than 25% of your order
- Invalid product type:
- NORMAL product type is not supported for stocks
- Invalid price
- Price outside the circuit limits
- Price not in multiples of tick size. If tick size is 0.05, then prices like 10.55, 10.60 are valid but 10.78, 220.11 are invalid. Zero price is only valid for market orders, for all other order types price must be non-zero.
- Price out of range: Price too far away from live price
- Invalid target & stoploss in case of Bracket Order (Every stock has specific max target & stoploss range defined by the stock broker)
- Stoploss order – Invalid trigger price (trigger already hit): If trigger price is higher than live price (for a sell stoploss order) or trigger price is lower than live price (for a buy stoploss order)
- Stoploss order – Invalid price: Price lower than trigger price for a buy stoploss order or Price higher than trigger price for a sell stoploss order
- Incorrect Product Type: An intraday order for a stock that has been banned for intraday trading
- Any other order parameters that can cause order to fail validation checks
Solution
- The best way to verify is to manually place exactly same order on your trading platform
- Note that some scenarios like invalid trigger price etc. depend on live stock price. So if you are trying to replicate the error then modify your trigger price/price accordingly
- Please verify & correct your order details. Complete order details can be checked at Orders page
