How to check if current position is not set instrument

[tkaboris]

Hi
I currently have following statement for checking there is no other position is opened before i enter a trade.
Position.MarketPosition == MarketPosition.Flat

However if i place same strategy on different instrument lets say i trade MNQ and 6B. I want both instruments act independently and be able to trade at the same time if setup occurs.
So i cant be using Position.MarketPosition == MarketPosition.Flat because it will cancel out another instrument if there is a valid setup.

How can i allow to trade on both instruments?

When a strategy executes, it is wholly independent and doesn't know
a darn thing about any other strategy, past, present or future, running
or not. The Position values for each strategy will always refer only to
themselves, it will never include status from other running strategies.

Even if it is the same strategy, started twice so you have two instances,
doesn't matter -- these instances won't know or overlap with each other,
everything is kept separate, including the Position.

Hello tkaboris,

Thanks for your notes.

If you have one instance of the strategy enabled on say the MNQ instrument and another instance of the strategy enabled on the 6B instrument, the strategies would not see each other's strategy position. A Strategy Position is a position that is created by the entry and exit executions generated by a strategy and is independent of any other running strategy’s position.

This means that Position.MarketPosition == MarketPosition.Flat could be used in the strategy to check if the strategy position of that specific strategy instance is flat.

Note that strategies cannot see orders placed by other strategy instances. This means that the strategy enable on MNQ would have its own separate strategy position.

See the help guide documentation below for more information.

Ok, what about if I have two strategies within the same strategy
strategy 1 - for long
strategy 2 - for long

If strategy 1 is already long, how can i make sure if strategy 2 gets a valid signal will enter long too? (only long not short)

EntriesPerDirection = 2;
&& (Position.MarketPosition == MarketPosition.Flat || Position.MarketPosition == MarketPosition.Long)

Strangly with above logic i get multiple output for longs ..

if(TrendTrade && TrendTradeLong) {
.........
}
if (ScalpTrade && ScalpTradeLong
                && (Position.MarketPosition == MarketPosition.Flat || Position.MarketPosition == MarketPosition.Long)
                && (BarsSinceExitExecution(0,"SLL",0) > 1 || BarsSinceExitExecution(0,"SLL",0) == -1)
                && (BarsSinceExitExecution(0,"PTL",0) > 1 || BarsSinceExitExecution(0,"PTL",0) == -1)

                && ((UseTimeFilter) ? ((Time[1].TimeOfDay >= Start.TimeOfDay) && (Time[1].TimeOfDay <= End.TimeOfDay)) : Close[0] > 0)
                && !((ToTime(Time[0]) >= 92500 && ToTime(Time[0]) < 94500) || (ToTime(Time[0]) >= 82500 && ToTime(Time[0]) < 83500))
                && (currentCount < X) //Has less than the amount of max trades specified
                && (dailyPnL > -DailyLossLimit) //Loss remains 'above' limit
                && (dailyPnL < DailyProfitLimit))        
                {
                    EnterLong(1,PositionSize, "STL");
                    Print("===============================");
                    Print("Entering Scalp Trade Long: "  + " " + Time[1] + "- " + CurrentBar);
                    ScalpLong = true;
                }​

Hello tkaboris,

Thanks for your notes.

If only a single strategy is being programmed and enabled then you would need to make sure that you are only checking if Position.MarketPosition == MarketPosition.Flat. This checks to see if the strategy position of the enabled strategy is in a flat position.

Currently, you are checking if you are in a flat position or if you are in a long position.

From the code you shared: (Position.MarketPosition == MarketPosition.Flat || Position.MarketPosition == MarketPosition.Long)

This means that if you are in a flat position or in a long position, orders would be placed by the strategy

ok but why do i have multiple longs prints?

[NinjaTrader_BrandonH]

Hello tkaboris,

Thanks for your notes.

Since the condition is true, your Print statements in the condition are called and are output in the NinjaScript Output window.

If you are using Calculate.OnEachTick for your strategy and the condition to call the Print statement is true, the prints would occur for each incoming tick that processes as long as the condition remains true.

If you use Calculate.OnPriceChange for your strategy and the condition to call the Print statement is true, the prints would occur for each change in price that occurs as long as the condition remains true.

Calculate: https://ninjatrader.com/support/help.../calculate.htm

Or, if you have multiple data series added to the script and you are not calling this code within a BarsInProgress == 0 condition, the print could be appearing when each data series is processing.

BarsInProgress: https://ninjatrader.com/support/help...inprogress.htm
Working with Multi-timeframe/Multi-Instrument NinjaScripts: https://ninjatrader.com/support/help...nstruments.htm

You could confirm your conditions are becoming true by adding prints one line above the position that prints out all the values being used in the condition in monitoring the NinjaScript Output window.

well its weird. I have two strategies TrendTrade and ScalpTrade,
TrendTrade never prints multiples but scalptrade does. Strategy on on price change. The print is only after entering long. So I have mulitple prints for long but entry only once..

Hello tkaboris,

Thanks for your notes.

I suggest adding debugging prints to the script to understand exactly how your custom strategy logic is behaving.

In the strategy, add prints to the script one line above the condition that print out the condition values being used to call the Print statement in question to see if those conditions are becoming true. And, print out the BarsInProgress in the current print you shared to see what BarsInProgress is processing when the print occurs.
