Some strategies work with the same open trades over and over again, but some strategies just once - if order exists posts: Label not unique(code 1). (Order already exists)
How to override Label not unique(code 1). (Order already exists) ???

Answering to my own question after some time !
Label must be unique to generate another order.
A simple Label will generate only one order.
Example of simple label:
public void onTick(Instrument instrument, ITick tick) throws JFException {
if (!ordersSubmitted)
{
ordersSubmitted = true;
// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL, TP, GTC; "note"
engine.submitOrder("Buy_EURCHF", Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "B");
engine.submitOrder("Sell_EURUSD", Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "S");
engine.submitOrder("SellUSDCHF", Instrument.USDCHF, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "S");
}}
One solution used by may is to auto generate a label with a unique number. Example:
protected String getLabel() {
String label;
label = "IVF" + generateRandom(10000) + generateRandom(10000);
return label;
}
private static String generateRandom(int n) {
int randomNumber = (int) (Math.random() * n);
String answer = "" + randomNumber;
if (answer.length() > 3) {
answer = answer.substring(0, 4);
But the simplest easiest way is to add to the label System.currentTimeMillis which is unique and continuously calculates time
in milliseconds since 1 January 1970. Example:
public void onTick(Instrument instrument, ITick tick) throws JFException {
if (!ordersSubmitted)
{
ordersSubmitted = true;
// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL,TP, GTC; "note"
engine.submitOrder("X"+System.currentTimeMillis(), Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "Buy");
engine.submitOrder("X"+System.currentTimeMillis(), Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");
engine.submitOrder("X"+System.currentTimeMillis(), Instrument.USDCHF, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");
}}
//:)

////label order - one label - one execution - messgae Label Not Unique if more ....
public void onTick(Instrument instrument, ITick tick) throws JFException {
if (!ordersSubmitted)
{
ordersSubmitted = true;
// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL, TP, GTC; "note"
engine.submitOrder("Buy_EURCHF", Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "B");
engine.submitOrder("Sell_EURUSD", Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "S");
engine.submitOrder("SellUSDCHF", Instrument.USDCHF, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "S");
}}
SOLUTIONS:
1. Using a simple counter
//public class Counter implements IStrategy {
private int counter = 0;
// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL,TP, GTC; "note"
engine.submitOrder("EURCHF"+counter , Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "Buy");counter++;
engine.submitOrder("EURUSD"+counter , Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");counter++;
engine.submitOrder("USDCHF"+counter , Instrument.USDCHF, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");counter++;
2. to add to the label System.currentTimeMillis which is unique and continuously calculates time
in milliseconds since 1 January 1970. Example:
public void onTick(Instrument instrument, ITick tick) throws JFException {
if (!ordersSubmitted)
{
ordersSubmitted = true;
// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL,TP, GTC; "note"
engine.submitOrder("EURCHF"+System.currentTimeMillis(), Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "Buy");
engine.submitOrder("EURUSD"+System.currentTimeMillis(), Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");
engine.submitOrder("USDCHF"+System.currentTimeMillis(), Instrument.USDCHF, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");
}}
3, Counter + System.currentTimeMillis()
//public class Counter implements IStrategy {
private int counter = 0;
// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL,TP, GTC; "note"
engine.submitOrder("EURCHF"+counter+"T"+System.currentTimeMillis(), Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "Buy");counter++;
engine.submitOrder("EURUSD"+counter+"T"+System.currentTimeMillis(), Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");counter++;
engine.submitOrder("USDCHF"+counter+"T"+System.currentTimeMillis(), Instrument.USDCHF, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");counter++;
4. getLabel
//////////////////

private int counter = 0;
private String getLabel(Instrument instrument) {
String label = instrument.name();

// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL,TP, GTC; "note"
engine.submitOrder(getLabel(instr), Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "Buy");
engine.submitOrder(getLabel(instr), , Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");

protected String getLabel() {

label = "IVF" + getCurrentTime(LastTick.getTime()) + generateRandom(10000) + generateRandom(10000);
return label;
}
private String getCurrentTime(long time) {
SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT_NOW);
return sdf.format(time);
}
private static String generateRandom(int n) {

}
// engine.submitOrder("LABEL", Instrument.EURCHF, IEngine.OrderCommand.BUY, LOT , Price, Slip, SL,TP, GTC; "note"
engine.submitOrder(getLabel(instr), Instrument.EURCHF, IEngine.OrderCommand.BUY, 0.001, 0, 2, 0, 0, 0, "Buy");
engine.submitOrder(getLabel(instr), , Instrument.EURUSD, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");
engine.submitOrder(getLabel(instr), , Instrument.USDCHF, IEngine.OrderCommand.SELL, 0.001, 0, 2, 0, 0, 0, "Sell");
/////////////////////////////////////

engine.submitOrder(getLabel(tick.getTime()), selectedInstrument, IEngine.OrderCommand.BUY,

return "IVF" + DATE_FORMAT.format(time) + generateRandom(10000) + generateRandom(10000);
}
private String generateRandom(int n) {
