MT4 EA that takes orders automatically with signals received by MT4/MT5

Hello, 

I want an expert advisor that I will manually put in the credentials of an MT4/MT5 account. 

And the EA job is to do the following

1) Open Trades
2) Close Trades
3) Modify SL and TP

Features

Risk in these 3 levels:
1) Very Low Risk -(20,000)
2) Low Risk - ($10,000)
3) Medium Risk - ($6,000)
4) High Risk - ($4,500)
5) Extreme High Risk -($3,000)

This is how the EA will calculate the lot size multiplier. 

the strategy works like this high risk 0.01 to 3,000 USD


So if the client deposits 10,000 and selects extreme high risk then the lot multiplier will be 0.01 *10,000 / 3,000
if the client deposits 10,000 and selects very low risk then the lot multipler will be 0.01 * 20,000 / 20,000

the system should have provision for symbol prefix and suffix depending on the broker. 

Also option to do symbol mapping infact of complete different labelling. 

eg XAUUSD mapped to Gold
