Indicator 'Currency' Is a Useful Program - indicator for MetaTrader 4

The indicator-informer Currency prints and writes into a file the following information:
1. currency pair;
2. the price of one lot in a deposit currency, i.e. value of margin when a position of 1-lot volume is opened for a chosen pair;
3. maximal lot volume possible for this currency pair with a set percent of balance and spread taken into account (stick to Money Management).

There are only two parameters in the indicator:
All_Pairs 
  true  - information is shown for all currency pairs (28 pairs);
  false - information is shown for the current security.

Procent - desired percentage of balance.

The following tasks are solved:

1. choosing the optimal currency pair in terms of costs;

2. calculating margin and spread costs;

3. stick to MM of your strategy.
