Need help for Quantity managment.

[Muroyal]

Hello All,

I have placed the query for placing order from AFL amibroker. with the below conditions.

1) first order should be 1;
2) If any order exited by Stop loss or target (sell or cover) the quantity should be 1;
3) if the stoploss or target not hit then the queantity should be 2; way means on next buy or short it will close exsting 1 quantity and place one more quantity and continue next trade;


Kindly help me on this how to trade with above logic. I have given which modifified but i am declaring the values as static in starting hence the it will not change;
Hoping any one will help me and fix the issue.

Next_QUANTITY=0;
