still no oco scripts/ea's for mt4?

after extensive searching, the only oco script/ea for mt4 i could find has a problem when removing the script from the chart, it freezes mt4 for 30 seconds. maybe someone can rescue this last vestige of oco capability in mt4?

actually, after an order is opened and the other order is cancelled, the script deletes itself as it should. there is just a problem trying to remove the script when the orders have not been opened yet. is there a way around this or will the code need changing?
