strategy triggered only once a day (using strategy builder)

[nothingtrader]

Hello! I would like to know if I can make my strategy to trigger only once after the conditions are met, even though the conditions might occur again in the same day.
Ex: enter short when the price touches yesterday's high for the first time. Only enter again the next day, when the variables of the condition will change (at the next 'yesterday's high')
Is it possible to achieve this in strategy builder? I have no experience in programming.

thank you!

Hello nothingtrader,

Welcome to the NinjaTrader forums!

Yes, you can use a bool which is a true or false value.

Require the bool to be false in the condition set that places the order.

Set the bool to true in the actions for that set.

Then when its been set to true, the condition will not trigger any more because it requires the bool to be false.

When you want a condition to allow new orders, set the bool back to false.


Below is a link to a forum post with helpful information about getting started with NinjaScript. I recommend starting with the Strategy Builder 301 video.

This would be very useful when I'd like to bypass a specific set from a strategy. But for backtesting it, I'd like the strategy to automatically become active again the next day, just until the conditions are met for the 1st time, then stop it again and rerun it the next day and so on. Like for example, I want to place a short only the first time price is touching yesterday's high. Thank you!

Hello nothingtrader,

You can set the bool back to false when Misc -> First bar of session is true.

You can have a condition that compares the Price -> Close to be equal to Indicator -> PriorDayOHL -> Prior High.

It works! Thank you very much!

Hello:
I have a strategy that only goes in long, I created a bool variable ReEnter=true and a condition ReEnter=true to make the entry and change ReEnter =False, but it still makes entries. How can I tell the strategy builder that I only want one post a day???I've seen this forum and I don't know if I'm doing it wrong or I don't understand it.
Thank you

Hello Emilio,

In the condition set that places the order, there will need to be a condition that requires the bool to be false.

In the action, the bool is set to true.

This should not be set back to false until, in a different condition set, Misc -> First bar of session is true.

Variable:
ReEnter bool false

SET 1

Condition:
.........
ReEnter=false

Do the following;
EnterLong.....
ReEnter=true

SET 2

Condition:
Bars.IsFirstBarOfSesion=true

Do de following:
ReEnter=false

Is correct????there are some days whit two or more trades.

Hello Emilio,

The bool starts as false.

The bool is set to true in set 1, when the action is allowed once.

The bool is reset back to false in set 2, at the start of a new session.

The bool must be false for the action to trigger.

Got it, thanks.
It is possible to have within the strategy in addition to a profit target and a stop loss a trailing stop???? How could it be activated if it were possible?
Thank you

Hello Emilio,

This is Jim, responding on behalf of Chelsea who is out of the office at this time.

A Trailing Stop can be used with SetTrailStop under Stops and Targets in the Strategy Builder. The Auto Trail behaviors will be controlled by the strategy internally, and will update based on the Calculate mode of the strategy.

If you would like to control your own stop loss to make a trailing stop you can do so by creating logic to control a stop market order submitted with ExitLongStopMarket/ExitShortStopMarket in Conditions and Actions instead of using SetTrailStop.

An example that demonstrates how custom auto trailing behavior can be created in the Strategy Builder can be found here - https://ninjatrader.com/support/foru...596#post806596

We look forward to assisting.

Hi, I have a strategy builder scheduled that only goes in long, I have programmed a trailing stop and I can't get it to work, can you help me ????
inputs: stop, trailstar, trailsize
type: double
Default: 60, 40 50
Variable: Stoplong - double - 0
SET1
Do the following:
EnterLong
Stoplong=0
SET2
Position.MarketPosaition=MarketPosition.Long
Stoplong=0
Do the following:
Stoplong=(Posotion.AveragePrice-(Stop));
ExitLongStopMarket(DefaultQuantity,Stoplong)
SET 3
Position.MarketPosition=MarketPosition.Long
(Default input[0]-(Trailstar))>Position.AveragePrice
(Default input[0]-(Trailsize))>Stoplong
Do the following:
Stoplong=(Default input[0]-(Trailsize);
ExitLongStopMarket(DefaultQuantity,Stoplong)

Is correct?????
Regards

Hello Emilio,

Take a look at the TrailBuilderExample I have provided you a link to in post #12.

Use a double variable to save the price of the next trigger point.

When the close price reaches the trigger point, call the exit to move this to the price, then save the price of the next trigger point to the variable.
