Sold price is much lower than SetStopLoss()

[op1031]

Hi all,

I am backtesting a strategy. I use the following code to set my stop loss. Most of the time, the stop loss triggered at the correct place, but once in a while, I see the sold price is much lower than the stop loss price. In this case, the stop loss was set at 1.21553, but the sold price was at 1.21251. Am I doing something wrong or is there a reason for this?

SetStopLoss("Target1", CalculationMode.Price, stop, true);
SetProfitTarget("Target1", CalculationMode.Price, target);
this.order1 = EnterLongStopMarket(2, true, this.SharesToBuy, entry, "Target1");

Thanks!

Hello op1031,

Welcome to the NinjaTrader forums!

With market or stop market orders, these can be affected by slippage. When the stop is touched the order will fill at the market price, which may have moved away from the stop price. This will be more pronounced in fast moving markets.

To check the calculated prices before calling the set methods, print the these with the time of the bar to the output window.

Hi Chelsea,

To check the calculated prices before calling the set methods, print these with the time of the bar to the output window.

I set the stop loss right before I make the EnterLongMarketStop order, and at that point, I was able to see the value of the stop loss which was 1.21553 in the debug mode, but the exit is 1.21251 for some reason. To be honest, I don't quite understand what I need to print... could you be more specific?

I checked on the minute data I have, and there were definitely a few candles that hit 1.21553, so I don't quite understand why the backtest simulator would not exit at the correct price.
I also noticed that my Exit time is always at half an hour. For example, it would print the exit time is 2/13/2019 7:30:00 AM or 7/15/2019 8:30:00 AM, and so on (It is always at the 30 minute mark. I wonder if my 1 HOUR primary time frame has something to do with it).

When I set the stop loss, I specify to use bar index = 2, which is the minute bar. I thought I set the stop loss and it would just execute the stop loss when the price is hit regardless of what time frame I use, am I mistaken?

Hello op1031,

Along with TraceOrders enabled in State.Configure, add a print that prints the time of the bar, the stop variable, and the GetCurrentBid().

We will need to verify that the stop variable value is at least 1 tick below the bid.

Stop order methods are attached to the primary series. If the chart is an hour chart, the stop would fill with close prices from the hour chart.

You cannot supply Set methods with a Bars series index. There is no parameter for this. The set methods will always be attached to the primary.

Sorry, I remembered it wrong. I set it at EnterLongStopMarket.

I just want to clarify how stoploss works. My primary is 1 hour bar. Let's say I set the stop at $100.30, the 1 hour bar at 9:30AM triggered my stop loss has a high of $100.50 and the low of $100.00. Will my stoploss gets executed at the end of the 9:30AM? or does it get triggered whenever $100.30 is hit?
My thought is that the stop trigger will execute whenever $100.30 is hit, as a result, it would generate a market sell order. Am I mistaken?

We will need to verify that the stop variable value is at least 1 tick below the bid.

I only have minute data and not tick data. Since the simulator doesn't have tick data, how does the simulator execute a market sell order?

Hi Chelsea,

I lost track of the trade, so here is a new example with trace log. To sum it up, it is a short trade with entry @ 1.17912, stoploss set @ 1.18, profit target @ 1.17824. The analyzer shows that the trade hit stoploss and exited @ 1.18104 which is the bid price of the hourly bar at 7:00AM.
So this means, stoploss doesn't execute when it's hit; instead, it executes at the bid price of the end of a primary bar. Could you confirm this is how it's designed?

How can I make the simulator exit at the moment the stoploss is hit? I am guessing the answer is that I have to have tick data, and a tick data series to sell when the tick data hits stoploss, is that correct? Can I set my primary series as tick then let setstoploss take care of the stoploss by itself?

I was reluctant to set my primary time frame to a lower time frame because I saw this in one of the samples so I thought the primary series always need to be in the highest time frame. Did I misunderstand?

Very Important: This secondary bar series needs to be smaller than the primary bar series.
Note: The primary bar series is whatever you choose for the strategy at startup.

Hello op1031,

This information does not tell us if the submission price is less than the bid.

Along with TraceOrders enabled in State.Configure, add a print that prints the time of the bar, the stop variable, and the GetCurrentBid().

Stop market orders fill immediately at market price when touched during trading hours.

Thanks for the explanations
The issue is resolved. I was not trading in the primary time frame, so I guess that's why it was giving out unexpected results.
