Hello Barros,

You are missing a close parentheses (i.e. ")" ) at the end of line 44.

[Barros]

There is other problem

Please JasonK,
Now, the error is not been showned, but the shperelatives and the textrelatives are not appearing on the charts.
Could you help me.

[eSignal_JasonK]

Hello Barros,

Add onAction2(); after line 44.

[Barros]

Another error: missing ..... line 45

Please JasonK, could you help?

Hello Barros,

After another look at your formula, it looks like the difference of 30 might be too restrictive. I cleaned up your formula a bit and added a formula parameter so you can adjust the value of the BB difference through Edit Studies. FYI, it's no longer a Formula Wizard formula, so you won't be able to modify it in the FW. Try out the version below and see if this works for you.

EFS not appears

Dear JasonK,
I downloaded the Barros BW#.EFS, but when I opened it, there was only a blanc page . Nothing written.

[eSignal_JasonK]

Hello Barros,

File Share didn't like the "#" symbol. Duh. Here's a new link with the file renamed. Download and save this to your \eSignal\Formulas folder.


Barros_BW.efs

[Barros]

Ok, JasonK, now it is working

Let me tell you:
The differences are +/-;
YM #F = 30
ES #F = 3
Do you beleive the changes that you made are ok with they?

Thank very much for your attention.

[Barros]

Better visualize the text and shaperelt.

Hi, JasonK,
You made a good work, but could you enhance the formula, changing the position of textrelative and shaperelative, to show them better?

[eSignal_JasonK]

Hello Barros,

Do you need both the text and shape to appear for each signal? Try removing one of the two and see if that will work for you.

[Barros]

Ok JasonK,
I can use only one of them. But is there a way to set the shaperelative or the text relative farther from the bars?

[eSignal_JasonK]

Hello Barros,

Absolutely. For the y-parameter input, add/subtract a fixed value to the high() or low(). Or add a value that is a %value of the high or low. It would look like this,

drawTextRelative(0, low() - 0.25, .... 

or,

drawTextRelative(0, low() - (0.001*low()),  ... 

You may need to change the 0.001 number to suite your needs depending on the symbol and interval of your chart.

[Barros]

Thank you very much

Thanks, JasonK,
Now it is working very well.
