Hi,

Here's a blocks diagram that I would like to convert to a RC indicator:

Didn't find a way to do it in RC.

Would you give it a try?

Steve

The following should be very near or match the values returned by indicator on the chart. Note however that ZoomStartDate has a chart context and will not work anyplace besides the chart.

Hi,

So far, so good.  It worked in a chart that I tried, but as you pointed out, only in a chart context.

Is there a way to also be able to get a watchlist column from this indicator or something similar?

I was able to do that with the following blocks indicator.  The Cumlator block turns off AutoSize which allowed the indicator to have the same values in a WL data column as the chart values.

Problem was that, for some unknown reason, the WL column kept blinking and I could not find a way to turn that off.  Is there a command or RC statement to turn off the blinking?

Steve

No, there isn't any sort of command I am aware of to get rid of the blinking. The WL Column really doesn't like having to reference a the chart context even if it comes from a Block Diagarm. It will do it, but as you have seen, only begrundingly.

OK

I'm sure the blinking was programmed in to detect / warn a programmer or user of some condition that the code generates.  Any idea what the purpose is?

I have not run into it with any other RC or blocks indicators I have used.

Thx

I really doubt that is the case. It just has to keep refreshing because it is trying to pull data using a block using a chart context.

Since that block doesn't have a WatchList context it just doesn't behave well on in the WL.It is designed to work within a chart, but each time it switches symbols to calculate the next symbol in the WatchList, the context of the block changes to a different chart.

That is why the chart will WL Column will start working if you unlink it from the chart. It is a bit surprising it works at all while still linked to the chart.

OK,  but other blocks indicators that I've put into WL data columns didn't blink.

The block that seems to set off the blinking is the Value for Date block which is exactly the one I needed to anchor some calcs to the chart at the left end.

Unlinking the indicator using the WL command does turn off the blinking but then I am locked into whatever left end date was active when that command was done, so then if I subsequently change the chart zoom, I have to repeat the process of creating a WL data column for the indicator in question, etc.

I'll work with it when needed.

Thx 4 your help!

Steve

Something like the following would allow you to adjust the date without requiring a chart context.
