Draw.TextFixed Changes Location Based on Chart Time Fram

[Joe_T]

Hello. I have an indicator that uses the Draw.TextFixed() method to place information on the price panel of a chart. The indicator works well in many circumstances (it compiled properly, etc.), but in certain circumstances it has odd behavior.

Let's say I am placing the fixed text at the lower right of the chart. In this case, it is the S&P500 cash chart. And, it is at night - when there are no price changes. When I manually change the time-frame of the chart from 30-minutes to 60-minutes - meaning fewer bars, and the scale of the chart obviously changes. Now, instead of appearing at the lower right of the 30-minute chart, the indicator now appears on the right-hand side of the chart, but mid-way up, instead of at the lower right.

This behavior did not occur in NT7.

I am currently re-drawing the indicator "On Price Change" per the indicator template to help save resources. What is occurring when the time-frame of the chart is changed, but there is no price change, and is Draw.TextFixed supposed to respond to that, or is the code now supposed to be able to respond to it?

If it's supposed to be done in code, what do you suggest?

Hello,

Thank you for the post.

DrawTextFixed should do as its name suggests and stay fixed.

I tried a simple test of making an indicator that just draws text, and then applied that to a chart with Calculate.OnPriceChange but I could not see the same result. I tried to disconnect and also tried putting it on an out of session instrument but did not see the movement when changing timeframes.

Could you try a simple test for me to see if you can reproduce this in any ways using the sample? If so, I would like you to note the steps used and also to save the workspace and provide that to me for review.

I have attached a script, please feel free to modify this as needed to reproduce what you are seeing. If you do need to modify the test, please include that back to me as well.

If you are not able to see the simple test result in the same moving, this could potentially be related to the logic you are using in the script. We could take a look closer into that if that were the case.

I look forward to being of further assistance.

Problem Resolved

This problem has been resolved. The problem is caused by the interaction of Scale.Justification with the Draw.TextFixed method. When Scale.Justification.Overlay is chosen, the behavior of the fixed text moving around the screen is reproduced. When Scale.Justification.Right is chosen, the fixed text remains in the proper location, regardless of what chart time-frame is chosen.

(As an aside, when the IsOverlay property is set to 'false' as in the test script you asked me to import, an extra blank indicator window was opened. So the correct set-up is to have the IsOverlay property set to 'true', and the Scale.Justification set to right, as in the underlying chart, and as above.)

On reflection, the Indicator Wizard doesn't really well cover the case where a text indicator is being added. And this would be a nice enhancement some day as it exceptionally confusing for all but highly skilled programmers.

Thanks for your help.

Hello,

Thank you for the reply.

I am glad the change of settings seems to have resolved this for you. I am still questioning what may be happening with the situation you described here.

If you still have the ability to reproduce this, I would still like to get a copy of testing workspace to see if I can also see this. I am not certain the movement would be expected as this specific tool should stay fixed in place.

I look forward to being of further assistance.
