Including other timeframes on the chart

[jones24621]

Jason K:

I am looking for something that I can't find in the E-signal Forum, and was hoping you may have the solution someplace. With the custom ma indicator, I need to know how many bars until a new bar is formed. For example, on a 50 tick chart with a 450 tick custom MA - a new line is formed every 9 bars (50 tick bars). I am looking for something similar to a TIB (time in bar) counter, but just counts the bars formed. In the above example, the counter would count 1 thru 9, for each bar formed - then start over with 1 again. At the end of the ninth bar, a new line would appear on the customMA efs, and the counter would start over with 1. Hope I explained it well enough. Just a repeating 9 bar counter, etc...Thanks...

Hello jones,

To get a bar count that resets every 9 bars you could simply create a global counter variable and increment this by 1 at each new bar by checking for the bar state with the getBarState() function. When the counter has exceeded 9, reset it to 1. The first time the counter is equal to 1, execute your code or draw your line. Try something like the following.

var cntr = 1;

function main() {
    if (getBarState() == BARSTATE_NEWBAR) {
        cntr++;
        if (cntr > 9) cntr = 1;
    }

    if (cntr == 1 && getBarState() == BARSTATE_NEWBAR) {
        // 9 50t bars have been completed
        // execute your code here
    }
}

bar count

Jason - Thanks for the input. I tried what you suggested, but wasn't sure how to execute the code - or to write it exactly. I am using a 50 tick chart, and want to count 1 thru 9 - or just mark every 9th bar or every 450 ticks. Any more help would be greatly appreciated...

Hello Jones,

Please post your code so I can see what you're missing.

Bar Count...

Jason:

Here is the efs I am using. It seems to work fine - but is there a way to may the arrows larger, or perhaps use a verticle line? I would prefer a verticle line. Thanks

Steve

var cntr = 1;

function main() {
if (getBarState() == BARSTATE_NEWBAR) {
cntr++;
if (cntr > 9) cntr = 1;
}

if (cntr == 1 && getBarState() == BARSTATE_NEWBAR) {
drawShapeRelative(-1,high(-1),Shape.UPARROW,"",Color.black,Shape.BOTTOM);

// 9 50t bars have been completed
// execute your code here
}
}

Hello Jones,

Use drawLineRelative() from 0 to positive infinity. Replace your drawShape call with something like below.

drawLineRelative(0, 0, 0, (1*Infinity), PS_SOLID, 1, Color.red, rawtime(0));

Draw Shape

Jason:

I tried this but it didn't work...any ideas why?

var cntr = 1;

function main() {
if (getBarState() == BARSTATE_NEWBAR) {
cntr++;
if (cntr > 9) cntr = 1;
}

if (cntr == 1 && getBarState() == BARSTATE_NEWBAR) {

drawLineRelative(0, 0, 0, (1*Infinity), PS_SOLID, 1, Color.red, rawtime(0));

//drawShapeRelative(-1,high(-1),Shape.UPARROW,"",Color.black,Shape.BOTTOM);

// 9 50t bars have been completed
// execute your code here
}
}

Hello Jones,

It's working on my end. Did you get a formula error? What version are you using?

[jones24621]

Jason - I didn't get an error - just didn't show any lines. I am on 7.9.1 E-signal...

[eSignal_JasonK]

Hello Jones,

Be sure that you saved the formula after making the changes. Then remove it from the chart and then reapply it. What symbol and interval are you using it with?

[jones24621]

Jason, I got it to work by merging the study with prices...Any way I can get it to stand alone as a separate oscillator in another window pane?

[eSignal_JasonK]

Hello Jones,

If you have setPriceStudy(false) in preMain() it will draw the lines in the non-price window, but the study will also have to return something to create a scale. Try adding return sma(5) to the end of main.

[jones24621]

Jason - that seemed to do the trick...Any idea of how to make the SMA invisible. I use a standard grey background? Thanks for your help. Much appreciated...

[eSignal_JasonK]

Hello Jones,

Change the color for the return value to the same color as your chart background using setDefaultBarFgColor(Color.grey, 0) in preMain or change the return value to a string using the .toFixed(2) method.

return sma(5).toFixed(2);

Hi Jason/Alex:

Is there a way to color the string returned by an EFS so that in the price label cursor tracking window that string would show up in a color of choice depending on its value? like other values on the chart whose color is based on the color definition of that particular study in the chart?

thnks,
