Fix five scripts

The five scripts are simple MT5 scripts or indicators that have been ‘saved as’ .mq4 for use in MT4. They have been written by different programmers.

They work poorly in MT4 causing ‘Do you really want to stop script’ errors or ‘not responding’ hangs. I have bundled them together as I expect many of them incur similar issues.

Your task is to get them working correctly in MT4. The first one requires a little further modification. 

Here are the details:

1. chgtf-all

I have attached the working MT5 scripts and .mq4 versions

- Fix the error ‘Do you really want to stop script chgtf-all’?

- I have created multiple scripts, one for each time-frame. Therefore I do not require the window that opens each time the script is activated so please remove this. You only need to do one as I will modify the code that you provide to create scripts for each time-frame required.

2. Deliniation_lines_365.

I attach the working MT5 script ‘Deliniation_lines_365.mq5’ for you to see it working correctly (365 means they go back for 365 days) and the original brief.

I also attach the  ‘save as’ mq4 version that I want you to fix. The problem is that the lines are appearing in the wrong locations and use of the script causes a  ‘not responding’ hang. I assign a Hotkey to activate the script. It is my preference to press the hotkey again and have the lines disappear - so the hotkey toggles the delineation lines on and off. If this is not possible the following script acts to remove the lines.

3. Object_Delete_Vertical_Line

Please find attached working mq5 version and mq4 version that causes ‘not responding’ hang. Please fix so it doesn’t hang MT4.

4. chart_period_change_up & down

Works in MT4 but occasionally produces an error:

Do you really want to stop script ‘chart_period_change_up’? Please fix this issue

5. Show_trade_levels_toggle

Please find attached working mq5 version and the mq4 version that does not work. Please make the trade levels toggle on and off with use of a hotkey applied to activate a script.

Thanks
