Hi,

I tried to create my first strategy based off the simple stochastic given in your wiki examples but seem to have some problems with it.

I am attaching the code and the output/debug messages which were obtained as output.

I am trying to trigger buy and sell based on the values of stochastic result[0]. But Buy and Sell seem to be triggered randomly. Can you please help. I know C programming but am completely new to java, so not sure if its a programming mistake.

Thanks,
Vamana.

I have also set a stop loss of 10 pips in my submitOrder command but the loss in some cases exceeds the 10 pips per the html which pops up after the historical tester is run. Is there something wrong with the way I have set stop loss?

Consider adding more logging statements in the decision points, see:
https://www.dukascopy.com/wiki/#IConsole/Logging_values

Previous_Stoch = indicators.stoch(instrument, period, side, fastKPeriod, slowKPeriod, slowKMaType, slowDPeriod, slowDMaType, shift);

Are you aware that here you calculate the stoch on an arbitrary period bar (most likely 10 secs)? See onBar description here:
https://www.dukascopy.com/wiki/#Strategy_API

if ((instrument == Instrument.GBPUSD) && (period == Period.FIFTEEN_MINS)) {

Consider filtering bars the opposite way, see:
https://www.dukascopy.com/wiki/#Filter_Ticks_Bars
This wise you will reduce the code nesting.

Previous_Stoch = indicators.stoch(instrument, period, side, fastKPeriod, slowKPeriod, slowKMaType, slowDPeriod, slowDMaType, shift);
Current_Stoch = indicators.stoch(instrument, Period.FIFTEEN_MINS, side, fastKPeriod, slowKPeriod, slowKMaType, slowDPeriod, slowDMaType, shift);

If you wish to use the same period here, then consider using the candle interval methods for indicator calculation, see:
https://www.dukascopy.com/wiki/#Indicator_Calculation/Calculate_indicator_by_candle_interval

stoploss = Double.parseDouble(myDF.format(bidBar.getOpen() + 10 * myPipValue));

Calculate the SL/TP price distance as it is done here:
https://www.dukascopy.com/wiki/#SMA_Simple

if ((myOrder.getState().equals(IOrder.State.CANCELED)) || (myOrder.getState().equals(IOrder.State.CLOSED)) || (myOrder == null)) {

if myOrder will be null, the condition will fail with the NPE, hence the last OR condition is redundant in either way.
Consider reducing nesting to make the code more manageable, e.g. the block which starts with the upper mentioned line could be simplified to:

if (myOrder == null || myOrder.getState() == IOrder.State.CANCELED || myOrder.getState() == IOrder.State.CLOSED) {
    canTrade = true;
    return;
}
if ((myOrder.getOrderCommand() == IEngine.OrderCommand.SELL && Previous_Stoch[0] < Current_Stoch[0])
        || myOrder.getOrderCommand() == IEngine.OrderCommand.BUY && Previous_Stoch[0] > Current_Stoch[0]) {
    myOrder.close();
    console.getOut().println("Order Closed");
    canTrade = true;
}
