trend ines

[tergar2]

I draw trend lines on an indicator at the botton of my chart, a CCI bottom panel from Woodies CCI CLUB,and after aI draw it, just use segment since I'm connecting 2 points, I unclick and the line disappears. I can draw on the candle portion up above and lines stay but not on CCI panel. Is it that it is an efs downloaded from Woodies club and cant accept such lines or should I just forget it.

If the indicator is painting the background then that could be covering the trend lines you are drawing. In that case right click the chart, select Properties and put a check mark in Draw Lines On Top of Price. That should make the trend lines visible again

Draw Lines on Top of Price

Alex,

In my chart window, I have a Moving Average. I see that eSignal defaults to drawing the PRICE candles OVER the Moving Average indicator.

Is there any way to toggle this, so that my moving average is drawn on top of the price candles?

At this time there is no way to do that. If you would like to submit a suggestion send an email to [email protected]

The feature, DRAW LINES ON TOP OF PRICE appears to be "broken"!!

I am using version 8.0 build 779.

Unless that means something else.... which it seems to... very confusing.

If you use a line drawing tool, the line is drawn over the price but if a study draws a line, the line is "below" the price.

Either ALL LINES should be drawn over OR studies should have this as part of their properties too.

That setting applies only to Trendlines. All graphic objects drawn by an efs (with the exception of the addLineTool() functions which draw Trendlines) will plot/draw underneath the price bars

Thanks Alex... you gave me an idea!

I modifed my TRO_HLINE study to use addLineTool.

I call the new study TRO_HLINETOOL.

See the magenta line at $36.40 is over the price bars!

One thing though... the line "vanishes" and then returns.

Is there something else I need to know?

Perhaps only update on close of bar?

At this time there is an issue with the tagName parameter in addLineTool() which is supposed to be fixed in one of the next releases.
In the mean time an easy way to resolve this issue is to use either removeLineTool() or clearLineTool() before using addLineTool()

buzzhorton,


Since you are using the same "tag" for the line when you draw it, at every tick it will switch state from being drawn to disapperaing (disappears as it draws over itself).

One possible fix is just to track the state internally to your efs:

Function preMain(){
nDrawn = 0;
}

Function main(){
.
.
.

if (nDawn == 0){
addLineTool(....);
nDrawn++;
}

}

You can then set nDrawn back to zero if you ever do want to get rid of the original line and draw a new one someplace else, or you could add nDraw as a paramter to the "tag" and draw multiple lines.

Thank You.
