Sending the limit orders through publisher api, but later required to modify the price if the symbol was not traded. Help me out of changing the price or cancelling the order.
No, you can't use the publisher to modify or cancel the order. Modify or cancel orders require order_id as input param and you can use only these sets of input params for the publisher. You will need the kite connect app for this.
