Script or EA, manual and automatic to set take profit & stop loss based on value of Change % Column

Hello,

I'd like to create (well purchase) a tool that sets the target take profit and stop-loss values in reference to the value in the %change column in the trade section of the toolbox.

I've used the following ranking system to express how important a particular feature is, from most important to least important:

"Extremely Important"

"Fairly Important"

"Important"

"Quite Useful"

"Would be nice"

 This idea may not be a 100% flushed out but I am open to discussing and finalizing the design concept.

My ideal program will have the following components:

1. You can set a stop/loss and take profit at a given %change for a new trade (buy or sell)). These could be var_stoploss and var_takeprofit. (Extremely important)
2. You can set up a trailing stop loss value after the var_takeprofit is met (also based on the %_change variable. (Fairly Important)
3. You can set a delay on the stop loss by either time or number of bars.(Quite Useful)
4. We can modify/add variables to a trade already in progress. (Fairly Important)
5. You can open 2 new trades (hedge) in opposite directions on the same symbol with the stop loss and take profit. (Fairly important)
6. Same as number 5 except the stop loss and take profit for each direction of the transactions can be different values. (Would be nice)
7. When modifying stop loss or take profit values it adds a comment to the trade and generates a notification/log which can be turned on or off as required. (Important)
8. It can be monitor purchases from other EA's and then modify their stop/loss and take profit. (So if another EA triggers a buy on SymbolX once it gets added to the trade screen in the tool box this script/advisor will take over it's profit/stop loss. (Fairly Important)
9. Updated values can be based on a particular ticket rather than symbol. (Quite Useful)
10. We can change all buy trades of a particular symbol to a selected stop loss and/or take profit with. (Important)
11. We can change all sell trades of a particular symbol to a selected stop loss and/or take profit. (Important)
12. We can change all trades of a particular symbol to a selected stop loss and/or take profit. (Important)
13. It can be used to trigger purchases based on other EA's / indicators sending a signal somehow. (Would be nice)
