Black Dog System Indicator for ThinkorSwim - Strategy

[BenTen]

@Billions I just loaded the original script on my phone and it doesn't seem to work.

Does anyone else have any luck with this working on the phone

Why create more studies when just changing inputs solves the question. Please try to understand the studies before requesting changes. As Tomski mentioned changing the macdlength to 7 solves it.
The revised one just changed the names from macdlength to blackdoglength.
I am curious what the "input MACDLength = 1;" does ?

@BenTen Hi thanks for posting this strategy. I've been messing around with it in equities and futures and it seems like it works better for the markets that are open close to 24 hours. With equities the after hours and premarket trading seems to give false signals and enabling and disabling afterhours through the settings changes the signals, which makes sense. The hour timeframe on equities seems like it gives pretty good SESup and down signals. One other issue is that when I create a scan for signals enabling/disabling EH does the same as above.

I've tried to define the market hours in the script but I'm fairly new to TOS. I'd like to be able to define just the market open hours:

def MarketOpenTime = 0930;
def MarketCloseTime = 1500;

Not sure if I'm doing this right or if there is an easier line of code to put in to disable after hours within the script. Thanks!

@MAYissues There is no need to modify the code. Just disable the extended hours from your chart settings and also exclude it from the scanner and it should work.

Thanks, I appreciate you getting back to me!

I've tried disabling the extended hours and no luck. When you scan for the BDup in the scanner it will seed with symbols that don't have a BDup on them but if you enable extended hours it will be there. I also have extended hours off and my scanner is still updating with new symbols afterhours.

Can someone help my alerts are not working no sound. Can someone add an alert to this study for me

Can someone help my alerts are not working no sound. Can someone add an alert to this study for me

alert( CrossDn, "BUY", Alert.BAR, Sound.Bell );
alert( CrossUp, "SELL", Alert.BAR, Sound.Chimes );

alert( UpCross, "BUY", Alert.BAR, Sound.Bell );
alert( DnCross, "SELL", Alert.BAR, Sound.Chimes );

Anyone know how to color in the space in the channel? i.e. make the area between the two 50's a different color than the normal background? Thanks

 

[horserider]

@hashy Add this to the code. Pick the color you want.

AddCloud(Havg, Lavg, Color.LIGHT_GRAY);

 

[hashy]

@horserider Perfect. Thank you!

how do i change the agg period to suit ticks chart? i trade specifically on 1000 ticks, would this be possible?

 

[horserider]

@Playstation NO Just think why not.

@Playstation There is no notion of time on Tick charts, so what you're suggesting is not possible

Ah! Got it now!

 

[hashy]

Today's question (ha ha)... What's the code to have a text box in the top left of the chart that shows the direction of the last BDog arrow? I've discovered AddLabel but am unable to get it to work correctly. As always, thank you.

 

[levilebo]

Just add the following 2 lines to the end of the study I posted above - it will give alerts when the arrow prints

Alert(buySignal, "MACD Buy Signal", Alert.BAR, Sound.Ring);
Alert(sellSignal, "MACD Sell Signal", Alert.BAR, Sound.Bell);

this is awesome. how do i now add these alerts to specific stock on thinkorswim. for example wheen the MACD crossovers on AAPL, how do i set that up

Curious did anyone get the Black Dog to work on the 30 minute or it's not meant for that?

 

[horserider]

@Trading51 This part of the code sets an agg period of 20 minutes. Any chart time frame over 20 minutes will stop the study from working. Several choices.
Erase or comment out this part of the study.
Change Def agg to the an agg period higher then chart time period.
Change this line " def agg = AggregationPeriod.TWENTY_MIN; " to "input agg = AggregationPeriod.TWENTY_MIN;"
That should let you choose an agg in settings.


# Black Dog Arrows------------------------------------------------------

# Change Aggregation Period to 20 minutes------------------------
def agg = AggregationPeriod.TWENTY_MIN;
def data = close(period = agg);

# 2 EMAs of Black Dogs--------------------------------------------------
def BDfastEMA=ExpAverage(DATA,20);
def BDslowEMA=ExpAverage(DATA,100);

# Black Dog UP for EMA20 crossing ABOVE EMA100-------------
def UpCross = if BDfastEMA > BDslowEma AND BDfastEMA[1] < BDslowEMA then 1 else 0;
Plot BDup = if UpCross then high else double.nan;

BDup.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
BDup.SetLineWeight(5);
BDup.SetDefaultColor(color.WHITE);
BDup.HideBubble();
BDup.HideTitle();

# Black Dog DN for EMA20 crossing BELOW EMA100-----------
def DnCross = if BDfastEMA < BDslowEma AND BDfastEMA[1] > BDslowEMA then 1 else 0;
Plot BDdn = if DnCross then low else double.nan;

BDdn.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
BDdn.SetLineWeight(5);
BDdn.SetDefaultColor(color.WHITE);
BDdn.HideBubble();
BDdn.HideTitle();

# END==========================================
