Closing all open postiions

What does everyone now use to cover all their existing positions in a strategy? I've been using: and only execute these two statements once, not on every update tick or recalculation (using RecalcLastBarAfter). Is this still the correct approach, or is there yet another undocumented keyword to achieve the same thing in one go? As I stated I only execute them once since I've noticed some time ago during my stress tests a strange but very rare occurrence. if I executed them every time, I eventually may get a long or short opened for no apparent reason.

What does everyone now use to cover all their existing positions in a strategy? I've been using:

Code: Select all

buytocover all contracts next bar at market;
sell all contracts next bar at market;

and only execute these two statements once, not on every update tick or recalculation (using RecalcLastBarAfter). Is this still the correct approach, or is there yet another undocumented keyword to achieve the same thing in one go? As I stated I only execute them once since I've noticed some time ago during my stress tests a strange but very rare occurrence. if I executed them every time, I eventually may get a long or short opened for no apparent reason.

I use a similar code segment, but I'm more comfortable resubmitting them every tick while there is a market position. In theory, they should also work when you only submit them once (i.e. for a one tick duration with IOG), but just in cause the order doesn't get through or there is some other quirk, I just keep resubmitting them until the market position is indeed flat.

I haven't experienced that they opened a position, so can't comment on that, though off course they shouldn't do that.

I've been sending them only once as you suggested and I also check MarketPosition_at_Broker to make sure it becomes 0 within a certain number of update ticks. If it fails to do so I send out alarms. I do the same with all my orders checking to make sure MarketPosition_at_Broker reaches the expected value. I do this as a constancy check for all my strategies. It has helped me uncover coding errors and a couple of bugs in MC itself, one of which I'm still trying to resolve, possibly due to a corrupted installation. I'll soon find out when the markets open again after I've done a repair then if necessary re-installed it.
