GAP UP Alert

[cpatte7372]

Hello,

Does anyone have an script that will send an alert if/when a stock gaps up by a certain percentage after yesterdays close?

Cheers

This is ugly, but it should calm you down a little

You know how to sound an alarm by now don't you?

David,

I'm getting the syntax error message that it cannot find getPrevOHLC.efs. I getting quite familiar with the language now. Does that error message mean that getPrevOHLC.efs should be in a default folder or in the root of the tree?

Cheers

you can either move the efs David wrote to the OHLC folder or replace the following lines
yestC= call("getPrevOHLC.efs", "Close");
todyO= call("getTodayOHLC.efs", "Open");
with
yestC= call("/OHLC/getPrevOHLC.efs", "Close");
todyO= call("/OHLC/getTodayOHLC.efs", "Open");

Alex,

Thanks.

I am now getting an ReferranceError message stating that "gap is not defined"

I can't see where I should define it.

Thanks

Substitute gap with a numerical value or if you want to be able to modify that value through Edit Studies then add
the following just below function main()
if(gap==null)gap=nn;
where nn is the numerical value

Alex,

So, do I replace the the nn with an numerical number in the actual script? Because i inserted it as you mentioned but it still keeps on telling me that gap is not defined.

thanks

Alex,

I even tried it by replacing where it says gap! with a numeric and still getting same error message.

Alex,

I only get the error when I attempt to run the formula in a chart, not when I debug it.

Thx

Delete (or comment out with a //) the following line
debug("Gap!")
Then replace gap with a numerical value in the following line
if(todyO+gap>yestC)

Alex,

I tested this by inserted a high number but it doesn't appear to work.

What do you mean by "it doesn't work"?
Are you still getting syntax errors or are you not getting any alerts?
If the latter did you add any logic for the alerts? FYI there is none in the script as it was posted. David left that for you to insert.

Alex,

I think I may have it. I'm going to work on it in the morning.

Thanks for your help mate.

Cheers
