Hey All,

I've been sim trading a strategy that calls an ATM when getting buy or sell signals, and last night copied it and took out the buy/sell actions and replaced them with playsound and drawarrow commands so it was a "signal only" strat.

I then ran both on live ES data, using signals generated by the "signal only" strat to manually enter trades in one of my brokerage accounts. All in a days work.

BUT... the "signal only" strat was generating calls that the sim trader never took, and in some cases sim trader kicked in a few bars later. The "signal only" strat appeared to follow the conditions in the strat perfectly, while the one that does the buy/sell was less predictable.

Any ideas on where I should look for errors?

FWIW the ATM call strategy is cut-and-paste from the factory example.

hi,
i try to understand : you have

1) your trading-signals/logic coded as an indicator to show arrows in the chart + give a sound

and

2) your trading-signals/logic as a strategy to start sim/live -trades

these 2 behave different.

right till here ?

No they are both strategies. The difference is instead of buy/sell as an action its playsound/draw bar.

The sound and draw one:

///</summary>
protectedoverridevoid OnBarUpdate()
{ ///GO LONG: Conditions followed by ATM Strategy execution.
if (VSuperTrend(14, TradingStudies.NinjaScript.Utility.MovingAverageType.SMA, 2.618, 14, TradingStudies.NinjaScript.Utility.SuperTrendMode.ATR).Signal[0] == 1
&& (ATRratio(14, 7, 1).Ratio[0] >= 1)
&& (ADXVMA_sharky_paint(6, true).Main[0] > ADXVMA_sharky_paint(6, true).Main[1])
&& (ECO2New2(7, 4, 21).Main[0] > ECO2New2(7, 4, 21).Signal[0])
&& Rising(ECO2New2(7, 4, 21).Main) == true)

{
DrawArrowUp("My up arrow" + CurrentBar, true, 0, High[0]+TickSize, Color.Green);
PlaySound(@"C:\Program Files\NinjaTrader 6.5\sounds\LongES.wav");
Log("ES Sound Only LONG signal", LogLevel.Information);

}
///GO SHORT: Conditions followed by ATM Strategy execution.

etc etc etc

The call ATM one has this instead of the drawarrowup, etc:

{
// ATM Strategy code cut-and-paste from NT
// Make sure this strategy does not execute against historical data
if (Historical)
return;
　
// Submits an entry limit order at the current low price to initiate an ATM Strategy if both order id and strategy id are in a reset state
// **** YOU MUST HAVE AN ATM STRATEGY TEMPLATE NAMED 'ES 2 w BE and Trail' CREATED IN NINJATRADER (SUPERDOM FOR EXAMPLE) FOR THIS TO WORK ****
if (orderId.Length == 0 && atmStrategyId.Length == 0 && Close[0] > Open[0])
{
atmStrategyId = GetAtmStrategyUniqueId();
orderId = GetAtmStrategyUniqueId();
AtmStrategyCreate(Action.Buy, OrderType.Market, 0, 0, TimeInForce.Day, orderId, "ES 2 w BE and Trail", atmStrategyId);

}
　
// Check for a pending entry order
if (orderId.Length > 0)
{
string[] status = GetAtmStrategyEntryOrderStatus(orderId);

// If the status call can't find the order specified, the return array length will be zero otherwise it will hold elements
if (status.GetLength(0) > 0)
{
// Print out some information about the order to the output window
Print("The entry order average fill price is: " + status[0]);
Print("The entry order filled amount is: " + status[1]);
Print("The entry order order state is: " + status[2]);
// If the order state is terminal, reset the order id value
if (status[2] == "Filled" || status[2] == "Cancelled" || status[2] == "Rejected")
orderId = string.Empty;
}
} // If the strategy has terminated reset the strategy id
elseif (atmStrategyId.Length > 0 && GetAtmStrategyMarketPosition(atmStrategyId) == Cbi.MarketPosition.Flat)
atmStrategyId = string.Empty;
　
if (atmStrategyId.Length > 0)
{
// You can change the stop price
if (GetAtmStrategyMarketPosition(atmStrategyId) != MarketPosition.Flat)
AtmStrategyChangeStopTarget(0, Low[0] - 3 * TickSize, "STOP1", atmStrategyId);
// Print some information about the strategy to the output window
Print("The current ATM Strategy market position is: " + GetAtmStrategyMarketPosition(atmStrategyId));
Print("The current ATM Strategy position quantity is: " + GetAtmStrategyPositionQuantity(atmStrategyId));
Print("The current ATM Strategy average price is: " + GetAtmStrategyPositionAveragePrice(atmStrategyId));
Print("The current ATM Strategy Unrealized PnL is: " + GetAtmStrategyUnrealizedProfitLoss(atmStrategyId));
}

So the the conditions that lead to an an action are the same. Is there anything in the call ATM code... wait... what's that close[0]>open[0]?

Hi MXASJ,

Are both strategies running on the same chart or different charts?

RJay

i know from some examples where the printed values of indicators hasnt been the same as the values using this indicator in a strategy - always because of a special + unique coding-problem.
so your arrow+sound is a plotting-thing + order-execution is a strategy-thing.
i see you use the ADXVMA -- thats one of the examples i am talking about -- i had trouble too with that some time ago.
here is a link -- have a look + test it .

ADXVMA strategy problem? - NinjaTrader Support Forum

Indicator output is different when invoked by strategy - NinjaTrader Support Forum

good luck --- and report please

vielen danke max. Before I get too carried away what would the Close[0]>Open[0] thing in the ATM start do? Only long after a postive bar?

"if (orderId.Length == 0 && atmStrategyId.Length == 0 && Close[0] > Open[0])" is the example ATM strat code from NT (what I'm using).

I'll try the tips NTJosh mentioned as well.

Also looking at splitting the strat (actually the ATM it fires) into two... europe open and NYSE open. Wider stops on the NYSE open.

But now I need to sleep. Strat running on sim account. G'nite!

... "if (orderId.Length == 0 && atmStrategyId.Length == 0 && Close[0] > Open[0])" is the example ATM strat code from NT (what I'm using)....

I believe those tell you orderId.Length == 0 means no pending order

atmStrategyId.Length== 0 means not in a current trade

if you find something different, let us know
thanks
