I need to modify existing trailing stop EA (look in attachment) to add simple functions.

Functions that now available:


1. At the moment this EA functions (trailing stop) works only for two open orders Buy and Sell, I need to make it work for many orders as possible. Should work too with orders that opened by hand.
2. Need to add function for automatically opening orders buy and sell or just one of them, at the specific time. For example two orders opens at 14:00 time, another two or one order opens at 23:00 and etc. Should allow 5 different times with ability to turn off opening by time.
3. The third important function  to make all existing functions, not visible for a broker, all the same functionality but, without placing the TP SL and TRAILING lines. So I will be able to select if I use invisible mode or visible.
3. Should be testable on mt4 tester.
4.Should work with All time frames.
