 /*
  * DON'T FORGET TO SELECT "ALL HISTORY" FROM ACCOUNT HISTORY TAB!!!
  * This script helps to calculate a summarised version of all trades
  * done in a particular financial year. It converts all sales and 
  * purchase transactions into the base currency.
  * 1. Loop through all HISTORICAL trades between a predetermined date
  *    range.
  * 2. Calculate PURCHASE & SALE amounts for each trade
  *    -  Only will calculate closed trades during the financial year 
  * 3. Calculate charges: COMMISSIONS & SWAPS
  *    - generally these will already be converted into their BASE currency
  *      and therefore no conversion will be necessary
  *    - it will be assumed that COMMISSIONS are negative amounts
  *    - SWAPS will be listed in the Expenses area (even though they may
  *      have a positive value and therefore be income)
  * 4. Calculate open and closing positions (stock)
  *    - positions that are open prior to the beginning of the year form
  *      the O/STOCK
  *    - positions that are open at the end of the year form the C/STOCK
  *    - the values of these are in the BASE currency
  * 5. Output calculations.
  *    - at the moment it's just to Print
  *    - you should be able to double check the P&L value against your actual 
  *			account's P&L value for the same financial year period
