Sorry if this has already been answered in another thread. I could not find an answer to this, but currently it looks like strategies can only be evaluated as frequently as once per minute. Are there any plans to increase this rate to say once a second or once every 5 seconds at least?

Thanks!

Hi,

This only applies to Fidelity data, though. Theoretically, a data provider can evaluate as frequently as on every tick or second. It actually depends on the provider.

(This has been discussed - sorry that I can't find the thread - and it was concluded that this activity doesn't make much sense anyway.)

Got it,

I currently have esignal. So just to confirm, wealthlab should have esignal support by the end of the year and then I should be able to execute my strategy logic once every second if I like?

Thanks

We're starting to work on eSignal, but our priorities are the deliverables for the 5.6 release. There's a good chance that the eSignal static adapter will be finished by the end of the year, but a streaming adapter isn't likely in that time frame.

If you use 1-second bars, then the Strategy will execute once for each new second bar in a streaming chart.

Trading 1-second bars... you're new to the trading business?

I've actually have an automated system running against IB against 5 second bars for a few months now. My natural inclination was to try and reproduce that exact functionality in wealthlab. I'm happy to hear why moving to 1 minute bars would be better (and hopefully more profitable).

Can you direct me to some threads where this was discussed?

Thanks

I'm not saying that. If you're happy with your profitable 5 second system, then that's fine with me. You can test and trade other scales and find out for yourself. It's just the natural inclination of beginners seeking to avoid risk to try to hide in smaller and smaller time frames.

Of course it really depends on the strategy itself. For example, if you want 1-second bars to build and trade Point and Figure charts, then that's perfectly valid!
