Maximo, a couple of comments on your detailed script:

I have a modified version of my script which I think fixes the gap problem. It is not as detailed as Maximo's script, I only am showing the changing of the colour on the indicator. It is somewhat similar to maximo's script in that it sets the indicator to one colour then overwrites parts of it with the second colour.

linecolor:=

if (ma3<hist(ma3,1),0,  {for ma3 downdard}

if (ma3>hist(ma3,1),1,  {for ma3 upward}

prev));     {for ma3 sideways}

[drawundefined=gap]   {This attribute is essential to prevent straight  lines being drawn when indicator is "undefined"}

[color=red]

ma3;  {default colour for indicator when it is not green}

[color=green]

if (linecolor=1,ma3,undefined);   {this leaves a gap on first bar upward but leaves last bar on graph filled}

if (hist(linecolor,-1)=1,ma3,undefined);   {this fills first gap upwards but leaves a gap on last bar of graph}

{ Between them these two lines of script cover all the required green area. Dont combine them into one compound if statement as it then fails to work on the last bar plotted}

Thanks blackdog!

Used your script and managed to remove the gap :)

[target=price]

ma3:= ma(C,30,E);

linecolor:= if(ma3<hist(ma3,1),0,if(ma3>hist(ma3,1),1,prev));

{no lines drawn when indicator is "undefined"}

[drawundefined=gap]

[color=red]

if (linecolor=0,hist(ma3,1),ma3);

[color=green]

if (linecolor=1,ma3,undefined)

Shows there's more than 1 way to skin a cat. Didn't know about [drawundefined=gap] and cant find it in the bullscript help.

Cheers!

[drawundefined=gap] is not in bullscript help. I found it used in darvos box script and a little experimentation showed what it does... As you say, more than one way to skin a cat... hehe...

[target=Price; category=Moving Average; Author=Max]

StartDate:=InputDate("Start date", date(2004,1,2));

HoldingDays:=BarsSince(OnOrSkipped(StartDate));

period := input("Time periods",28,1);

bar := ma(2*ma(C,int(period/2),W) - ma(C,period,W),

int(sqrt(period)), W);

{Flag the StartDate}

begin:=If(bar>=PREV(undefined),PREV(undefined),bar*Holdingdays);

[color=lime; name=up; width=1; linestyle=solid]

if(begin=0,if(bar>=hist(bar,1),bar,bar),undefined);

[color=dark orchid; name=down; linestyle=solid]

if(begin=0,if(bar<hist(bar,1),bar,undefined),undefined);

[color=rgb(230,230,230); name=down2; linestyle=solid]

bar2 := (hist(bar,1)+bar)/2;

if(begin=0,if(bar<hist(bar,1),bar2,undefined),undefined);

[linestyle=pricecolor]

[color=dark green] if(begin=0,bar>=hist(bar,1),undefined);

[color=crimson] if(begin=0,bar<hist(bar,1),undefined)

No Rounders it's for BullCharts software.

CMC already has them built in.

Backtest before trading.
