Very simple but EA to be made with one main feature but info meter is required detailed.

The EA should only set TP and SL( Both Optional, We can set one at the time or no one at the same time or both active at the same time)
1. We active trade ourself , But in The EA this should ask if what the the TP and SL in form of USD we need. We'll put the Exact Required profit and or loss. This EA should calculate and set the tps and Sls itself to all the trades, and when we change the USD profit from info meter , this should edit the TPs and SLs accordingly all the trades on average, 

2. in Info meter we need , details ,

*like what we already the tp and sl in USD,
**a box with latest change to be done in running trades , (means if we want to change the required profit and or loss this should be instantly edited after we apply in chart box of required USD amounts.

***what will be the TP sl points avaerage , 
****what is leverage on account
*****what how much is lot size being trade on account.
Remember to check the strategy on Gold pairs as well.
******any more info meter , the Developer suggest.
