Hi, I want to post a new order from the POST back page according to the execution of last posted order. To post an order, Access Token is necessary. We are using checksum value as an access token. For ref {"order_id":"171016001168332","parent_order_id":"","exchange_order_id":"","order_timestamp":"2017-10-16 17:34:17","exchange_timestamp":"","status":"REJECTED","status_message":"BO: auto square off executed","placed_by":"ZJ9729","user_id":"ZJ9729","tradingsymbol":"SBIN","exchange":"NSE","transaction_type":"SELL","order_type":"LIMIT","quantity":1,"filled_quantity":0,"pending_quantity":0,"unfilled_quantity":0,"price":254.55,"average_price":0,"trigger_price":0,"product":"BO","validity":"DAY","variety":"bo","tag":"","checksum":"09314f12efbf432830d3efb7a83f5dcde9a58fd208a9197b7f47e422d3dcde0d"}.
