That's smart!

Very smart!!!

But could you please show me how to imply it to the code?An example perhaps?

PHP Code:


			
Print("Parameter X is ",X," and should be XXX");

before OrderSend function I set
Print("Ask is ",Ask," and stoploss will be ",sl," and takeprofit will be ",tp);
I also set stoploss level and takeprofit level before that.
Like this:
sl=Bid-SL*Point;
tp=Bid+TP*Point;
and only after I put print...

Thank You Shinigami,
You are awesome!!!

It works fine for me

You are a very good programmer!!!

MQL4 · #**145** (**permalink**) 07-30-2007, 07:00 AM

Shinigami,

I need Your help:

Before, it was:

PHP Code:


			
extern double TakeProfit = 20;

Then, I changed it to

PHP Code:


			
extern double TakeProfit = 400;

And the parameters, the inputs for the EA still show 20!!!!!!!!!

What's the problem?

Thanks in advance.....

MQL4.

Shinigami · #**146** (**permalink**) 07-30-2007, 12:11 PM

After you compiled EA and started testing it, its properties (settings) are written down into a file. You need to change them manually.
If you wrote TP = 400 in the EA, then it means you set default value to 400.
In order for the EA to use that value in strategy tester you need to set it in the EA settings. Or simply use default values (there is a button for that, but I have no idea what is it called, my MT4 is russian).
Anyway just change the value in the properties.
I also recommend you setting best values as default values - each time you compile an expert that is attached to a chart, default values are being used.

Sorry, nope. Can't figure it out myself. I'm still bad with indicators.

MQL4 · #**148** (**permalink**) 07-30-2007, 03:24 PM

Well, can someone make all of the bars green, and make the bars :

22:55 and 16:30 red?

Challenging, huh? Or maybe easy for You.

God Bless You all!!!

I love You!!! Thank You, I am so happy right now!!!

Thank You!!!

Perhaps someone can modify this, It currently paints the bars red, at 22:50 and 16:30, but the other bars are still normal colors.

If I get chance I'll see if I can improve this for you.

regards
zu
