Bid/Ask spread indicator updating even if no trades take place

[RedDuke]

I am trying to create an indicator that will display spread between bid and ask and display it on the chart. Method OnBarUpdate will only be triggered if there is an actual trade. But there are many instances when bid/ask spread will change many times between the trades for some instruments. Is there any method that will be triggered if anything changes in order book?



Thanks,

Hi RedDuke,

Yes but this is outside of what we provide technical support for at this time. I can point you in a direction. Take a look at the VolumeProfile indicator source code to get an idea of what can be done.

Hi Ray,

I took a look at volume profile, and it also seems to be only updated when the price ticks, and not when info changes in DOM. I realize that you do not provide support for custom development, but I would really appreciate if you just point me to an indicator or method which is being trigerred whenever something changes in DOM.

Thanks,

Hi Dierk,

Could you please clarify on Not Supported?

Is it possible to access MarketAnyliser data through an indicator?

"Not supported" in this case means that we do not provide support for the functionality discussed.

Thanks. Will try to figure it out.

So basically we cannot trigger any code from changes in the bid price(or size) or changes in the ask price(or size)?

We can only trigger code from trade prices?

I would like to set up some type of alert that will sound if the bidask spread exceeds a certain amount. So is the best we can do here is measure the spread at each trade price event?

This will be supported by fall time frame.

Please find attached an indicator that displays the current best bid/ask prices whenever it changes in the order book.
