/*====================== MONEY MANAGEMENT / COMPOUNDING ===========================================
Changing the value of mm will give you several money management options
mm = -1 : Fractional lots/ balance X the risk factor.(use for Mini accts)
mm = 0 : Single Lots.
mm = 1 : Full lots/ balance X the risk factor up to 100 lot orders.(use for Regular accounts)
***************************************************************************************************
RISK FACTOR:
risk can be anything from 1 up. 
Factor of 5 adds a lot for every $20,000.00 ($2000-MINI) added to the balance. 
Factor of 10 adds a lot with every $10.000.00 ($1000-MINI) added to the balance.
The higher the risk,  the easier it is to blow your margin..
