Opening position in intrabar

[GoodBro]

I would like my strategy to open a position when the price exceeds a standard deviation line in the chart. However, the position is not taken until the start of the next bar(for example 5-minute candlestick). Sometimes in fast markets, this can mean a huge difference in entry price compared to the price of the standard deviation line.

How do I tell my strategy to take trades *exactly* when the line is crossed, instead of waiting until the start of the next candle bar?


Thank you

Hello GoodBro,

Thank you for your post.

If you would like your strategy to calculate more frequently than on bar close, you would need to change the Calculate setting to OnPriceChange or OnEachTick. OnEachTick means the strategy would calculate on every single tick. OnPriceChange means it would calculate once for each price change.

See the help guide link below for more information about Calculate.

Thanks for your repply.
This is done but still it doesn't work.
See in attachement an example with the bollinger bands.
Since I don't want to wait the bar close to take a position I set BID has to cross below the lower band. It has no effect when I try the strategy in playback or in live condition on Sim101.

Hello GoodBro,

Thank you for your note.

If the expected trade(s) are not appearing, this would indicate that the condition to place the order is not evaluating as true or the order is being ignored for other reasons.

To understand why the script is behaving as it is, such as placing orders or not placing orders or drawing objects when expected, it is necessary to add prints to the script that print the values used for the logic of the script to understand how the script is evaluating.

In the strategy add prints (outside of any conditions) that print the values of every variable used in every condition that places an order along with the time of that bar.
Prints will appear in the NinjaScript Output window (New > NinjaScript Output window).

Also, you could enable TraceOrders which will let us know if any orders are being ignored and not being submitted when the condition to place the orders is evaluating as true.

Below is a link to a forum post that demonstrates using prints to understand behavior and including a link to a video recorded using the Strategy Builder.

Hello Brando,
Thanks for the advices.
I switched TraceOrders to true and added prints so we are now able to monitor what is going on through the Output window.

I noticed that orders are not submitted when the conditions are true.

I tried to only change the "Cross Below/Above" conditions to "Less/Greater". It works pretty good even though this is not what I am looking for. I want only one order to be sumbitted at the cross moment.

I feel like cross below/above can't work with Bid/Ask price data on Calculate.OnPriceChange/Calculate.OnEachTick.

Hello GoodBro,

Thank you for that information.

CrossAbove/CrossBelow requires the use of a series object. The Bid/Ask options in the Strategy Builder use GetCurrentBid/GetCurrentAsk which are not a series object. That means that the Bid/Ask cannot be used for CrossAbove/CrossBelow conditions in the Strategy Builder.

If you would like to have your orders submit the moment that the Bid/Ask is above or below the Bollinger bands, you would need to check if the Bid/Ask is less than or greater than the Bollinger Band and use a Calculate mode of OnEachTick or OnPriceChange. A bool could be used to have a single entry order placed. For example, you could create a bool (initially set to false) that is flipped to true when your order entry condition returns true. Then, you could check if the bool is true followed by calling EnterLong/EnterShort and flipping the bool back to false. This would mean that one entry order would be placed since the bool would need to be true to place the order.
