Exiting Cover Order and Bracket Order for a Particular Trading Instrument

Bracket Order and Cover Order are multi-legged orders and canceling the bracket order and cover order for a particular trading instrument there is no direct mechanism available from the API provisions supplied by the brokers. Hence here is the Amibroker AFL code to do the exit by reading the orderbook and processing the pending cover order and bracket order from the orderbook.

Supported Brokers : Aliceblue, Tradejini, Zebu

Why Exiting Cover Order and Bracket Order automatically is required?

To Build a Intraday stop and reverse models using Bracket Order and Cover Order with protection.

To implement the Exit Bracket Order I had designed a prototype model which can be later used in your AFL code to simply your coding requirements.

Parameter Controls

We can classify the modules into two types

1)Main Module (Exit Bracket and Cover Orders.afl) – used to cancel/exit the BO and CO orders for a particular trading instrument

2)Header Module (ExitBOCOOrders.afl) – used to parse the orderbook and to cancel the BO and CO orders (this AFL code needs to be placed under the Amibroker\Formulas\Include folder)

Main Module (Exit Bracket and Cover Orders.afl)

#include <ExitBOCOOrders.afl>


Symbol = ParamStr("Symbol","RELIANCE-EQ");
Pcode = ParamList("Pcode","BO|CO",1);
trigger = ParamTrigger("Trigger Button","Cancel Orders");

if(trigger)
{
resp = GetOrderBook();
CancelOrder(resp,Symbol,Pcode); //output in string format
}

Header Module (ExitBOCOOrders.afl)

//store the file under the name - ExitBOCOOrders.afl under the Amibroker\Formulas\Include folder

uid = ParamStr("Client ID","TS2499");
user_apikey = ParamStr("user_apikey","86cbef19e7e61ccee91e497690d5814e"); //Enter your API key here
api_secret = ParamStr("api_secret","8e8b207de43446c65f379bf2145b62fc"); //Enter your API secret key here
s_prdt_ali = "BO:BO||CNC:CNC||CO:CO||MIS:MIS||NRML:NRML";
broker = ParamStr("Broker","tj"); //Broker Short Code - ab - aliceblue, tj - tradejini, zb - zebu, en - enrich
