Nice idea!

 

Very structured code!

 

 

 

 

Let's examine it a bit...

 

If you click on the trendline and drag it to one side, you will see another trendline sitting where it was before.

 

If you click on that trendline and drag it to one side, you will see yet another trendline sitting there.

 

The reason being this section of the code:

 

if PlotOpenCash <> 0 and time >= OpenCash then

 

 

MC will evaluate this condition time >= OpenCash at every bar.

If this condition is TRUE, MC will draw a trendline at "OpenCash".

 

At the next bar, MC will evaluate this condition again.

If the condition is true, it will draw another trendline (at the same place).

 

MC will draw a new trendline, again and again, at the same place, until end of the day.

 

 

Although the duplicated trendlines do not affect the chart, it will consume precious CPU power.

If you have a few indicators opened, it will slow down your computer.

 

 

To fix the problem, all you have to do is take the multiple condition away:

if PlotOpenCash <> 0 and time = OpenCash then

 

 

you can do the same with OpenNewYork.

I was sure that they were a problem with the lines

 

Tams, you have Xray eyes

 

only > makes the difference from a wrong code to a correct code.

 

ThanX for the pedagogic explanation

Nice idea!

Thanx for your words of encouragement

 

The most I've learned comes from this forum

 

And this indicator was possible only with your gentle and clever support

//-----------------------------------------------------
	inputs:

PlotOpenCash( 	1   	),
PlotOpenNewYork( 	1   	),

 

 

I prefer to use

 

PlotOpenCash( True ),

PlotOpenNewYork( True ),

 

 

I found True/False is more intuitive at the Format Study window.

 

plus,

in EasyLanguage,

 

if PlotOpenCash = true then...

 

can be written as

 

if PlotOpenCash then...

 

 

1. "True" is implied.

2. the code looks cleaner without so many equal signs.

 

 

 

just a personal preference... makes no difference to the effectiveness of the code.

Dear Tams

 

I agree with you ; Programing is an art.

 

Because I'm a lazy animal..

 

...I write down 0/1 oftenly in the format window instead of true/False wich is more source of faults.
