MT4 script

Hello I need mt4 script

The script will go over all open charts on terminal

And for every chart do these 4 steps:

1. Remove all indicators from chart (not EA)

2. Add 3 indicators (I can input their name)

3. Change timeframe  (I can define time: 1,5,15...)

4. Change zoom level  (I can define zoom level 1-6)

If this helps I found these codes for key presses: http://forum.mql4.com/ru/14463
