1. Sorry, I trade each account separately since I am not an RIA doing master/sub. I am not sure they support what you are trying to do at all.
   
2. No, orders are cancelled, and that's it. I always cancel all my own orders at 3:59 to simulate this in backtest.
   
3. I would not do this if I were you, rather I would separate the logic of deciding upon an allocation and trying to execute towards that allocation, and run the latter every morning. the downside is then you introduce some continuous rebalancing, so then you need code to prevent unnecessary/small orders, etc etc. it gets tedious.

Hi Simon,
Thanks for your response. As to 1), I just heard from Q that they DO NOT support master/sub accounts. So I wll have to call my customer, obtain his password, and do it as an individual account.

2) OK . I don't know what I had seen that suggested that order_target orders would remain in force. I can no longer find the reference in Q 's help documentation.

3) Well I was just trying to avoid having Q generate unnecessary computer cycles performing the same weekly or monthly analysis every day. But maybe I should just store the desired results (rather than orders) to context variables, and run a daily task against that, e.g.

desired positions: 5240 shares of TLT limit 121.80
2122 shares of SPY limit $222.33
etc

daily procedure would check portfolio against that and resend orders accordingly.

Any reason not to do that?

Thanks
Serge

Yes that is the sort of thing I have been doing. If you are directing orders (IEX) there may be a cancellation fee, but regular SMART orders should be free.

Thanks Simon

@Serge did you find a way to execute an algo through the master RIA account?

From what I have read from this thread it seems that you need to hook up an algo for each subaccount. If you have many clients, this is really going to be difficult (imagine updating your algo when you have 200 accounts!).

HI Mohammad

No there is no way to execute through the master account. :<(

Yeah updating the accounts for 200 odd accounts would be a bitch... I only have about a half dozen that I need to run on these algos . Unfortunately.
(I'd rather have more accounts, as I'm a greedy sob...)

Bottom line, you'd better not have to stop and start that algo too often. So make damn sure you've backtested the hell out of it before running on that many live accounts. Of course, we know there are going to be things failing on Q's side (server glitches, power outages despite redundant servers, software updates, etc, etc) . Who knows how often this brings down the algo?

Nor can one simply write a batch file to automate the starting/stopping. Because all my clients use the security devices I cannot use a batch file. My computers are still relatively primitive beings that still have a problem with anything requiring sight and character recognition... lol.

I would love this functionality, even if only to implement some 'robo-advisor' algos for friends and family.

Hey guys, I noted the feature request, thanks!
