A system generated X trades across different assets and at the end of the run() I want to turn some of them Phantom (say, because the exposure to a particular asset would be above acceptable).

What would be the way of doing this in a for(open_trades) loop?

Calling the broker and begging him to cancel the over-exposed trade?

soooo funny...

There are no 'overexposed' trades placed...yet...There could be some over-exposure, IF newly generated trades are placed - so I want to turn some of them phantom.

Regardless of a reason: what's the way to change a pending trade to phantom?

Hi @Zheka,

I guess it depends on what you actually mean by "generated", "pending", "placed", etc.

It sounds like you're in a single Bar, correct? (I.e., you're not trying to do this on a later Bar after the trades were long ago entered & filled?)

So, don't enter a trade until you know whether you want it to be real or phantom.

Accumulate your "generated", "pending", desired trades in an array, and at the end of the run() spin through the array entering real or phantom as needed to "place" them correctly?

HTH.

A "pending" trade is a "pending" trade. And there is a clear advantage of having "risk mngt" as a separate module, usable on top of any other existing system without having to modify it with parallel "order accumulation/ tracking mechanism"/arrays, etc.

The solution is simple : (ThisTrade->flags) |=TR_PHANTOM , but a "higher level interface" for doing this, e.g. via tradeUpdate(), would not harm.

If the trade is still pending, exit it and open a phantom trade instead.

Why "exit - re-open", if simple setting of a flag works just fine?

Because I don't know if it works just fine, or will keep working just fine.

Exiting / re-opening the trade with ALL the exact same parameters (except phantomness) is cumbersome.

Please provide a way of accomplishing this via tradeUpdate() (e.g with negative NewLots) or some other simple way.
