Hi Backkettle:
Using the @Configurable annotation is very simple. You declare this annotation before the PUBLIC variable in variable area at the beginning of the strategy (the variable must be public). Some examples:
//Strategy configurable variables
@Configurable("Instrument to use:")
public Instrument myInstrument = Instrument.EURUSD;
@Configurable("Period to use:")
public Period myPeriod = Period.ONE_HOUR;
@Configurable("Risk value (100/risk):")
public double myRisk = 0.02;
@Configurable("Take Profit:")
public int myTakeProfit = 50;
@Configurable("Stop Loss:")
public int myStopLoss = 15;
@Configurable("Difference Value in Pips:")
public double myDifference = 10;
// Time specifics (related to server time - GMT)
@Configurable("Control time:")
public boolean myControlTime = true;
@Configurable("Trade weekends:")
public boolean myTradeWeekends = false;
@Configurable("Beggin Trade hour:")
public int myBeginTime = 7;
@Configurable("End trade hour")
public int myEndTime = 21;
// RSI Specifics
@Configurable("RSI Min:")
public double myRSIMin = 41.0;
@Configurable("RSI Max:")
public double myRSIMax = 59.0;
@Configurable("RSI interval:")
public int myRSIInterval = 14;
@Configurable("Before trigger value:")
public double myRSITrigger = -2;
@Configurable("Order inverter")
public boolean myOrderInverter = true;
The resulting window when strategy starts:
