Hi,

I tried to load indicator from EA using this ChartApplyTemplate function. 

But I don't know how to load with specified indicator parameters, When I tried with template it was load by default params.

Like iCustom function with parameters, how to pass indicator parameters to load on template when a button is clicked in EA?

Any suggestions

Thanks.

if u post ur code, it would be easy to help u.

Open notepad and drag your template file (with extension *.tpl) into it. You can see what settings are stored in the template.

Regarding inputs , i give a sample from my expert. It is saved in the following format in the template file.

<expert>

name=PPan

flags=343

window_num=0

<inputs>

LotSize_1=0.01

LotSize_2=0.02

LotSize_3=0.03

LotSize_4=0.04

LotSize_5=0.05

LotSize_6=0.1

LotSize_7=0.2

LotSize_8=0.3

LotSize_9=0.4

LotSize_10=0.5

LotSize_11=1.0

LotSize_12=2.0

LotSize_13=3.0

LotSize_14=4.0

LotSize_15=5.0

</inputs>

</expert>


I changed the settings directly in the template file. It worked perfectly. Although i did it on expert inputs, it should work fine for indicators too.

Thanks for the reply.

As you said should I edit every time update when I change parameters in EA so that it will apply.


In your example, how can you change the input LotSize_1=0.01 to LotSize_1 = 0.5

That's what I'm looking for. So that I can pass different parameter from EA to indicator.
