OnMarketData And Chart Update question

[rt-trader]

Hi,

Just want to check that I properly understand the different update process here.

OnMarketData will update each time something changes in level 1 data.

A chart will update on each tick.

So - if I wish to display say the current ask price as text on a chart the changes in that ask will only be reflected on a chart when a new tick is processed (even though the level 1 data may have changed within the script).

Is this correct?

And - if it is, is there any way to force an update on a chart without a tick being processed.

Thanks

Hi,

Your understanding is correct. We do not support user controlled forced display refresh at this time since you can easily overload the CPU by forcing updates on a chart on each change in L1 data.

Ok,

Thanks for the (very speedy) reply Ray...
