How the Rapira EA Works

The EA performs a range of operations: it determines levels for orders placement, automatically calculates the most appropriate lot size, moves trades to breakeven, supports and modifies them, etc.

Following technical tools are at the heart of the Rapira EA: Larry Williams' Percent Range, Moving Averages Convergence/Divergence, Moving Average of Oscillator.

All trades will be performed in the direction of the current market trend only. All other signals, which are in conflict with the trend, will be ignored.

Money Management of the Rapira EA includes 3 options:

The first option is Money Management=false: Money Management is disabled and lot size is not intentionally calculated. Trading is based on a fixed value set in Lots_NoMM.

Two other options of Money Management depend on a percentage ratio of balance/funds/risk, i.e. value in MM_RiskPrcnt.

If MM_RiskPrcnt is less or equal to 6%, the lot size is calculated using the most standard formula. The third option is the most aggressive one, when MM_RiskPrcnt exceeds 6%.

Default StopLoss parameter is equal to 0. In this case StopLoss is calculated basing on the minimum price for the previous trading day. A user can set any StopLoss level.
