OrderParams orderParams = new OrderParams(); orderParams.quantity = 50; orderParams.orderType = Constants.ORDER_TYPE_MARKET; orderParams.tradingsymbol = "NIFTY21N0318000CE"; orderParams.product = Constants.PRODUCT_NRML; orderParams.exchange = Constants.EXCHANGE_NFO; orderParams.transactionType = Constants.TRANSACTION_TYPE_BUY; orderParams.validity = Constants.VALIDITY_DAY; orderParams.tag = "myTag";
