I am fluent in Easy Language but I cannot get the IBPlugin code to work in a strategy in any way, shape or form. I am requesting for anyone to post a strategy in Easy Language that uses the IBPlugin and performs successfully. I would like to see the exact implementation of how the IBPlugin is arranged within the easy language code - primarily the buy and sell statements.

You may block out proprietary components of your code if you wish. I'm just trying to get an idea of how to make this work.

I have installed the IBPlugin Demo strategy and it works. But I cannot figure out how to use the code when actual Buy and Sell orders are used. Any help would be much appreciated. Thanks, James

The sample that is installed along with IBPlugin and be tested on MultiCharts should run
perfectly without any problems also on TS.
This sample is discussed in this video:

https://youtu.be/lH3GE_pDm48?list=PLYD3 ... dcECuxa954

The example demonstrates the most important features.
Please mind: Other than in your code, all code is within the "initialized" condition.
So it is exectued once.

You wondered about the code multiple times executed but you definitely made the mistake to place
it outside the initialized flag. Then of course, it is executed with each call of the script and this is a matter
of EasyLanguage and not of IBPlugin.

Find attached the plugin sample and a small script just placing a MKT order ONCE each time you attach
the script to the chart.

Unfortunately, when i sent you a small code sample, i did the same mistake and leave some code placing orders
outside the condition flag.

So the new small example has corrected this. Please check out.

First of all, there is no BUY statement in your small ts_signal strategy. This is what you have:

Code: Select all

inputs:  
	Length( 9 ); 
	
	
variables:  
	Avg( 0 ) ;
	
Avg = AverageFC( Close, Length ) ;

if Initialized = 0  then begin
	
	once clearprintlog;

etc., etc., etc.,

If I attach that strategy/script to a chart it will just buy a market order the second I run it and do nothing else. But why would I want it to do that? I want it to buy when this is true:

Code: Select all

If close < Avg then begin

Or any IF/THEN statement for that matter.... that is what a strategy is. When I move that line of code below the:

Code: Select all

if Initialized = 0 then begin

then nothing happens. When I move it above it the strategy will immediately send a market order and then do nothing else.

I will post the entire version of the code I'm experimenting below again. And if you could please tell me why it's not working. I have even simplified it to do only one thing. If the close is below the AVG, then send a sell market order. Right now it does nothing.

Code: Select all

First of all, there is no BUY statement...

:
There is, please look a bit closer: order_attribute_str="#1=1#53=BUY#6=MKT#49=";
The order is defined by an attribute string. The possible attributes are listed in the help.

If I attach that strategy/script to a chart it will just buy a market order

Yes. This is what it should do. The intialized flag is intended to execute the BUY MKT order just once. When this code is called, initialized is set to 1 and so the code within
condition is not executed again.

I remember that you first copied the code, changed it and placed your orders outside the "initialized" condition and you wondered why
it placed so many orders. Well, this condition in the sample is intended to avoid exactly such situations.

if Initialized = 0 then begin

If close < Avg then begin

When the script is called first time, it executes the code below Initialized. If the average condition is given, you are lucky, if not,
nothing will happen, because this code section never called again, because initialized is now 1.

When you move this code outside the initialize section, the code is executed each time close < Avg. And i guess, this can be the case very often.
And so no wonder all code below this condition is executed multiple times.

But i don't want to discuss EL code logic here. Please have understanding for this. It is focused on IBPlugin functions.

Again: The sample script places all IBPlugin functions within the initialized condition to execute them only once for demonstrating purpose.
And this is exactly what happens.

I suggest: Outcomment all IBPlugin function calls. Make console Printouts instead. Run the script. Once you think the console printouts occur like
intended, enable IBPlugin function calls and all should be fine.

IBPlugin code that just need to be called once, keep it inside initialization flag. This applies at least for connect the symbol mapping function.
