 * The pip values for the function come from http://www.interbankfx.com/calculator.htm

 * Inputs
 * 1 stoploss1 - what is your stoploss i,e, 10, 20, 30 etc pips, ensure that trailingstop is
 *              - less then stoploss1
 * 2 risk1 - how much of your accounts free margin are you willing to loss
 *         0.03 for 3%, 0.1 for 10%
 * 3 std_or_mini - enter "std" for a standard or demo account, where the minimum transaction size is
 * 				   1 lot of 100,000 of the base currency or enter 
 * 				   "mini" - where the minimum transaction size is 1/10th 
 *                  the size of a standard lot, or 10,000 of the base currency.  
 * 4 symbol2 : the symbol your dealing with e.i. "EURUSD"
 * The function determines your accounts leverage
 * and returns the number of lots that you can then purchase
