Hi

I saw this and want it for MC. Does anyone have something similar. It is from CQG and looks super neat.

I think that if you make a Range chart, then you'll only need an indicator that colours the bars depending on how many transactions were executed at the bid and the offer as a percentage of the total trades executed for that bar. So certainly not impossible or very hard to code, but I haven't done such a thing myself.

I will give it a try, but my EL skills are still only empryonic

As simple solution with Upticks/Downticks would be:

Code

input: BarWidth (8);
vars: BGColor (0);
Plot1 ( Low + (Upticks / Ticks)*Range,"+",green,green,BarWidth );  //Set to Barhigh
Plot2 ( Low,"+",green,green,BarWidth  );						//Set to Barlow

plot3 ( High,"-",red,red,BarWidth );						//Set to Barhigh
Plot4 ( Low + (Upticks / Ticks)*Range,"-",red,red,BarWidth );	//Set to Barlow


//Midline
if Upticks / Ticks >=0.5 then BGColor = cyan else BGColor = magenta; 
Plot5 (Low+Range/2,"Mid1",BGColor ,BGColor ,3 );					// Set to Right Tick
Plot6 (Low+Range/2,"Mid2",BGColor ,BGColor ,3 );					// Set to Left  Tick

Hi
This works great. However, I am trying to get a smoothed version of this. Below my attempt, simply averaging the individual plots. the links are from CQG website showing their smoothed (by 3 bars!?) version.

My question is hich plots would you smooth here, to get a similar result: All four like below, only one & four or only two & three etc??

My attempt, left out the midline here:

Code

 input: BarWidth (8),Thickness (3), Smoothing(10);
vars: BGColor (0);



Plot1 ( average(Low + (Upticks / Ticks)*Range,smoothing), "+",green,green,BarWidth );  		//Set to Barhigh
Plot2 ( average(Low,smoothing),"+",green,green,BarWidth  );							//Set to Barlow

plot3 ( average(High,smoothing),"-",red,red,BarWidth );											//Set to Barhigh
Plot4 ( average(Low + (Upticks / Ticks)*Range,smoothing), "-",red,red,BarWidth );						//Set to Barlow

thx really appreciate it

May you can try this ... not tested because have no real-time data for the moment and here.

Code

input	:	barwidth(6); // input for plotwidth of HL bars in indicator 
input	:	smoothing(3); // average of bars to be calculated for upticks and downticks

var	:	var1(0); // variable for upticks
var	:	var2(0); // variable for downticks
var	:	var3(0); // variable of ratio of up- minus downticks compared to sum of upticks & downticks
var	:	var4(0); // average of ration for the last bares defined from smoothing
var	:	var5(0); // variable for range of current bar
var	:	var6(0); // variable for plot as a breakpoint for indicator plot (rounded to tick)


var1	=	upticks;
var2	=	downticks;
var3	=	absvalue(upticks-downticks)/(upticks+downticks);
var4	=	averagefc(var3, smoothing);
var5	=	range;
if var1 > var2 then 
	var6	=	low+(roundinst(range*var4)) else
	var6	=	high-(roundinst(range*var4));


plot1	(high, "h1", red, red, barwidth); // plotstyle Bar High
plot2	(var6, "l1"); // plotstyle Bar Low
plot3	(var6, "h2", green, green, barwidth); // plotstyle Bar High
plot4	(low, "l2"); // plotstyle Bar Low

thx for the help...but..
the roundinst is not recognized. what is that ?
