Help requested with the "inTimeInterval"function
I doubt that anyone will try to understand what you are doing. The post is a total mess.
Use the SRC button to post code and arrange the code in sensible lines and blocks.
This forum is mostly coders helping coders, you will not find many willing to help you correct the awful code created by EA builders.

For large amounts of code, attach it.- We hate EA builder
- You couldn't be bothered to learn mql4, therefor there is no common language for us to communicate.
- There are only two choices: learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem, but we are not going to debug your hundreds lines of code.
- EA builder makes bad code counting up while closing multiple orders.
- EA builder makes bad code Bars is unreliable (max bars on chart) volume is unreliable (miss ticks) Always use time
- EA builder makes bad code Not adjusting for 4/5 digit brokers
- EA builder makes bad code not adjusting for ECN brokers.
- EA builder makes bad code not checking return codes.
- EATree uses objects on chart to save values - not persistent storage (files or GV+Flush.) No recovery (crash/reboot.)
Firstly, sorry for the mess of code, it appeared Java script was not activated, so the buttons to paste the code correctly where not visible.
Secondly, as you can see in my text I'm not asking anyone to do the job for me, I'm simply asking if there is a function that I can use on the local scope. I've searched for it in the documentation, but was unable to find it.
Below the code as it should be pasted.

Good afternoon everyone, With the help of EA-Builder I created the code below and afterwords I adjusted the code to my preferences. I'm possibly the newest of newbies to mql4. It's an indicator that places a symbol on the chart when volume exeeds the set value in the specified period, I'm using it for gold en CFD's. Currently the indicator uses the function "inTimeInterval". I learn from the documentation that this function can only be used on a global scope. I understand that this means it effects the entire indicator. The indicator worls fine, but to cover the whole of a day I need to place it several times on one chart for a single time frame. Is there a way to change the code on a local scope so I can have 4 periods each with it's own set volume value ? (as you can see I have been preparing that)
The code is three comments below.
Thanks in advance,
Robert
