Black Dog System Indicator for ThinkorSwim - Strategy

[Buckbull]

Why when I copy and paste the script and save it in studies or copy the link and go to open shared items and save it in studies it plots nothing on my chart ?

 

[Billions]

Can someone help I've been using Black Dog System On 5 min chart, however I never see the white black dog arrows. I don't know what's wrong

 

[BenTen]

@Billions On which ticker do you not see the white arrows?

 

[Billions]

futures ES /MES

 

[Billions]

I wonder if I have the right script. What is the new script in post # 82

That was a modification made following a request from @hashy to display a label that shows the direction of the last BDog arrow? Details in the modification history in the study

Oh yes I see do I add this to the script that Ben originally posted or can I replace that script to add this label. Also I am not seeing a white black dog arrow

@Billions You can either add my modifications to @BenTen originally posted study, or use post #82 which already has that functionality incorporated in. Either approach is fine. For more info, read the change log in that study. Was that not explicit enough? Regarding the White BlackDog arrow, if you load that study on a 5 minute chart of AMZN, you'll see the white arrows. Make sure you have your expansion space increased, I set mine to 22.

This may sound dumb But where do I find the expansion area?

 

[tomsk]

@Billions Go to Chart Settings > Time Axis. You can see the expansion area setting to the right.

Ok that's not it mine is set to 100

@tomsk Does this study work on futures

Since I had some free time earlier today I took a closer look at the WHITE arrows on the original study. I believe part of the confusion was that WHITE arrows were used for BOTH a BDog Cross Up as well as a BDog Cross Down situation. This might be the basis of some of the recent confusion that was caused. I have now updated the code to adjust the positioning of the cross up/down arrows and as well as modified the color schemes for signals.

BDog Cross Up - Green
BDog Cross Down - Pink

Great gonna load it up and see if I get a signal. I was seeing the yellow and purple lines and arrows but no white black dog let’s see if this script works better. I will keep you posted Thanks for the update I appreciate it.

@Billions Best way to test is to create a fresh new chart and re-add the indicator. It seems from that screenshot you have multiple indicators that plot arrows. Sometimes other arrows may be in the way of the white arrows.

OR...

The white arrows have been changed to a different color. I think that's what happening here.

Gotcha will do Thank you

 

[Billions]

@BenTen Sorry to bother you can you send a picture of the chart showing the black dog white arrows. Its driving me crazy. Thanks

 

[BenTen]

@Billions Didn't see any white arrows for today or yesterday, but it was there from a couple days ago. Very rare to spot.

@Billions
Have you loaded up a 5m / 100day chart or something? You don't get the black dogs every day. Sometimes not for weeks at a time.
Another way to do it... add 20 and 100 EMAs on a 20 minutes chart. Find where they cross. Go to your 5m chart and that's where you should have a dog.
