Plotting arrows when Fast MACD moving average turns up or down

[Tradwell385]

Hi, I'm trying to create an indicator that plots up or down arrows simply when the fast macd moving average turns up or down. I have a macd that changes from red to green when it turns up and green to red when it turns down, but I would also like an arrow to plot on the chart when this happens. I've tried using the rising/falling under misc to create this but it is not working correctly at all. Any help would be greatly appreciated.

Thanks,
Ian

Hello Ian,

You have Rising selected?

Do you have the input series set to the MACD indicator with the MACD plot selected?

In the actions have you added an action to draw an up arrow?

Is this being drawn at the close price?

A screenshot of what you have would be helpful in this situation where you are asking about a condition you have setup.

Hi Chelsea,

I have pasted what I have in the script so far... it could be way off. "Mom" is the name I have for the fast macd average, and "top dog momentum" is the macd indicator, in case that's confusing.

Just to give you an idea of what I'm looking for, I would like arrows to be plotted on the chart when the indicator turns up or down / red or green. Where the yellow arrows that I have drawn in are where the indicator turns up/down and red/green. I have provided a picture of my screen to give you an idea of what I'm talking about.

Hello Ian,

I think you are wanting to have IsRising() be equal to true (or false) and not equal to itself, as its always equal to itself.

The Green and Red integer variables need to be set to something or will default to 0.
Also the value of the indicator needs to match whatever Green and Red are being set to.

Print these values to see why they are or are not matching
Print(string.Format("{0} | TopDogMomentum1.Mom[0]: {1} == Green: {2}", Time[0], TopDogMomentum1.Mom[0], Green));

Use unique tag names to draw multiple objects.

Thanks,

I set it to "IsRising" but it just posts a ton of arrows on the screen instead of just one arrow when it goes from falling to rising. It seems to plot an arrow on every candlestick where the macd "is rising." Since the macd indicator that i'm using is someone's proprietary indicator, I'm not sure what to set the red and the green to... do you suggest I try to create an indicator that mimics the proprietary macd and then try to work off of that to only show one arrow when it turns from red to green? I'm not sure what to do here lol.

Hello Ian,

The Green and Red integers are variables that are part of your script and are not part of the TopDogMomentum1 indicator.

You are comparing these to the indicator's Mom value TopDogMomentum1.Mom[0].

Do you want this code? You can choose to remove it..


Yes, IsRising() will be true on every bar that the series is rising.

If you would like the previous bars value to be falling you would need to track this and code this in your condition.

Create a bool variable and set this to the value of IsFalling() at the bottom of OnBarUpdate() below the condition.

In the condition require the bool variable to be false. This would check that the series was falling on the previous bar and on the current bar is rising.

I have deleted the green and red integers. I am also trying to create a bool variable in the strategy builder, but I'm not sure how to do this... are there any resources for creating that condition in strategy builder?

Thanks again, you've been a lot of help so far.

[Tradwell385]

Or, even better, would you be able to provide screen shots of how to create this Boolean variable? Thanks

Hello Tradwell385,

If you have not already, be sure to watch the Strategy Builder 301 training video.

Also, below is a link to a forum post with helpful information about getting started with NinjaScript.

Attached is an export of a strategy created with the strategy builder that demonstrates this concept.

Hi Chelsea, thanks for the reply. The example looks like it is based on a MACD cross. Instead of the macd crossing each other, I would like the arrows to come on the screen only when the fast macd turns up or down, no crossing involved. Is that a possibility? I'm really confused on what variables to use in this instance.

[NinjaTrader_ChelseaB]

Hello Tradwell385,

I don't have your indicator, and this example is demonstrating an idea and is not meant for you to actually trade.

When you mention:
"Instead of the macd crossing each other, I would like the arrows to come on the screen only when the fast macd turns up or down, no crossing involved. Is that a possibility? "
Yes, this is a possibly and what I am demonstrating in this example I have provided you. Drawing an object when a series is rising on the current bar and falling on the previous bar.

The bool MyBool is what is used to track if a series is rising or falling on a previous bar.

Hi Chelsea,
Is there a way that I could add other conditions to this strategy that use a multi timeframe approach? I know how to add it to the strategy, but which "set" of the strategy would I add that I would like the MACD to be rising on two other timeframes? Would it be under "set 1" of the example indicator that you sent me?
