Library of trading functions (position size, open, close position etc.) from the EAs "Ocean Breeze" and "Graalino-Pro".
It can be of big help for novice traders as an example how to handle trading events.
It calculates the size of position from the RISK (%) given. Forget about pips, lots, ticks, digits etc. Take a pro-approach. It works on any financial instrument regardless of currency's name, leverage, lot digits, account's currency, broker etc.
The library works for several years at several different brokers on more than 50 currency pairs, metals, etc. This library is a Public Domain.
