Multiple MIS orders 5 secs apart fails, only the order is accepted

KKannan

Hi everyone

I use the following java client code to place multiple orders at different price in 5 secs interval, now only 3qty. The first one is accepted, but other fail with return message as null.

int qty = Integer.parseInt(qtyFld.getText());
double halfPerc = (stock.ltp/100) * 0.5;
for(int i = 1;i <= qty;i++) {
OrderParams orderParams = new OrderParams();
orderParams.quantity = 1;
orderParams.orderType = Constants.ORDER_TYPE_LIMIT;
orderParams.tradingsymbol = stock.name;
orderParams.product = Constants.PRODUCT_MIS;
orderParams.exchange = Constants.EXCHANGE_NSE;
orderParams.transactionType = Constants.TRANSACTION_TYPE_BUY;
orderParams.validity = Constants.VALIDITY_DAY;
/**
* First order starts at next support, and minus half perc multiles of that downwards
*/
double nextLevel = (i == 1)?stock.getNextSupport():stock.getNextSupport() - halfPerc * i;

orderParams.price = nextLevel;//stock.getNextSupport();//Double.parseDouble(limitPriceFld.getText());
orderParams.tag = "myTag"; //tag is optional and it cannot be more than 8 characters and only alphanumeric is allowed
try {
Order order = ZerodhaAlgo.kiteConnect.placeOrder(orderParams, Constants.VARIETY_REGULAR);
System.out.println(order.orderId);
}catch (KiteException ke){
System.out.println(ke.getMessage());
}
try{
Thread.sleep(5000);
}catch (InterruptedException ie){
ie.getMessage();
}
}

Apreciate any help as to why this is so.

Thanks

We suggest enabling debug mode and share the complete stack trace in a private message. Also, please take a look at this support article.

Thanks, let me try to enable debug and see if that show anything meaningful.

Debug showed me it is the problem with tick size, so i changed it according to the nse guidelines and it is working alright now.

Thanks for the debug idea to find out the issue.
Anyway if it helps here is the tick size as per nse, price is 250 to 5000, then 0.1, 5000 to 10000 it should be 0.5 and above 10000 it is 5.

You can get tick size from the instruments master API.

Thanks, that will be lot cleaner.
