Any questions from newcomers on MQL4 and MQL5, help and discussion on algorithms and codes - page 117

 
Rustam Bikbulatov:
would I be paying for it?
Well, if someone with a lot of time can do it, you might get lucky. But otherwise, yes, time is money, sorry ;)

Or try to do it yourself, and you'll get help here - help is only for those who are learning on their own and fail at something.
 
Artyom Trishkin:
Start writing. What doesn't work - ask - we'll help.

Or do you want us to do it for you?
I wanted to connect these indicators, but there is one error. I've been struggling all day

Show me your code, where you are trying to connect them, and what's wrong?

Please paste the code with SRC button to see what you're trying to do, instead of uploading these codes to your system, they are already too much.

Artyom Trishkin:
Show your code, where are you trying to connect them, and what are you failing to do?

Please use SRC button to see what you are trying to do instead of uploading these codes to your system - there are already too many of them.
I wish I knew what that magic button was.
 
Rustam Bikbulatov:
if I knew what the magic button was.

Oh well.

Read the help on how to use the forum. Do you want a link, or can you find it yourself?

another funny thing

double OP = 5.00000

TP = (OP/100);

Print("TP= ",TP);

2017.02.09 21:36:03.650 2015.01.05 04:00:00 martin H1-1 USDJPY,H1: TP= 0.5

I don't understand since when do you divide 5 by 100 to be 0.5

I've got it figured out - the terminal does not support different colours for some reason, it just takes what is already there in other functions

In objects? Bullshit.
