Demand Index Alert

[cpatte7372]

Hello,

Can someone please help tweak the attached demand index to alert me when it crosses 0.5.

Thank you

The attached revision will play a sound when at the close of a bar the Demand Index has crossed either way 0.5

Hi Alex,

After testing the modified efs I found that it was alerting after the DMI passed through 0.5 and not when it actually was 0.5. So I tried to tweak the line by replacing line 121 with the following:

if(DMI_2=<0.5 && DMI_1=>0.5||DMI_2=>0.5 && DMI_1=<0.5){

however this gave me a syntax error that I couldn't figure out. Instead of the =< I think I need a 'setcompute' commnad added somewhere. I wonder if you could help me when you get a chance.

Cheers

The syntax error is caused by => or =< which should be respectively >= or <=

Hi Alex,

I made the corrections as you suggested, however I'm still not be alerting unil after the bar has closed - however I no longer get the syntax errors. This leads me to think that either I should include the setcomputeon (open) somewhere in the efs or its because I'm using bar replay to test it and may be when I use the script when actually trading it will alert me exactly when 0.5 is penetrated.

Would you concur?

Cheers

In my first reply in this thread I do mention that the efs was set to sound an alert only at the close (ie completion) of a bar.
Anyhow attached is a version that will work in real time and will sound one alert when 0.5 is crossed either way.

Alex is it possible to make a demand index like the one you have in the form of a histogram with the outline of the histogram outlined thickrer than the the bars of the histgram like woodies cci indicator where the outline is a thick blakc color and a drop dwn hst another colour

Many thks

Yes it is possible. At the end of the script replace return DMI; with return new Array(DMI,DMI); then in preMain() add two setPlotType() statements to define one of the plots as a line and the other as a histogram. Also add a setDefaultBarThickness() with the desired value to plot a thicker line. For the correct syntax on setPlotType() see the EFS KnowledgeBase under EFS Function Reference->Colors, Constants and Flags
