Newbie programmer question

New comment
 

Hi There,

I need to remove the price data that the indicator is displaying (separate window) and show plus and minus values that will be above or below a zero line. I have looked at functions MathRound and NormalizeDouble, but I am still confused. I spent all day yesterday trying to solve this problem. :(

Can someone offer some much needed advice, and could you throw in an example - that would be great?.. I am still learning MQ4, after all..

Many thanks.

Indicators are still new to me but I would look on code pages 1 and 2 and 3 at the standard indicators posted there and choose to study the one closest to what I want to do and edit it (slowly) to fit my purpose.

I already have. I am now looking at MACD code to try and find a way around my problem. Day 2...

If you want to show data about a zero line you need to do it in the separate window . . . trying to do it in the main window is a nightmare . . . you have to scale the data all the time the chart is moving.

Status update...

Okay, so I have figured out how to change the separate window price values from x.xxxxx to -x.x or x.x. All I had to do was swap the variable type from double to int. My intention is to have different levels for TP/SL and support/resistance and trade negative correlations

Problem solved, right? Wrong. Now I cannot see any lines or anything. I am only a newbie at this and still trying to find my feet, I understand some elements of coding.. But I fear this is a bit past my (ahem) knowledge.

I have posted the code, so if anyone wishes to offer a newbie coder a helping hand, then the beers + kebabs are on me..

Your lines are probably off chart . . . look at the values in the separate window using the Data Window to check that the values are within range.

The values are 9000000000000000 and -9000000000000000.

Is it worth me putting this question in the job section?

 

What is the goal?

What is the value range you are charting?

Consider making values a percentage of a range.

*edit - if you had graph paper how would you put the goal on the graph paper?

Jobs go in the Jobs section not questions . . . just work through it logically, add Print statements for all the variables that make up those values, then check the journal/log . . . I'm doing the same for my code now, my current log file is 400 MB, it's fun reading. ;-)
