Hi Pete, On the TTM squeeze I wanted to setup a trigger (Plot) on the COLOR of the BAR. For Example if the COLOR is LIGHT BLUE or YELLOW then setup an alert. I see you did something similar in the video above. I am planning to use the color of the bar along with the MACD and stochastic indicator. I wrote the initial lines of code, but I am not sure how to get to the Yellow Bars.
Thanks
Hilario

Hi Hilario,

The first step is to get the value of the Histogram from the TTM Squeeze indicator. Because the change in color is dictated by the value of the histogram compared to it’s relationship to the zero line as well as the value of it’s preceding bar. The color change from Cyan to Blue is defined as the histogram above zero, the current bar lower than previous. The we add an element that checks that the histogram was trending higher before current bar. This way we are only alerted on the first blue bar after a series of Cyan. The signals below the zero line are handled in similar fashion. The last two lines are for the alerts.

declare lower;

input price = CLOSE;
input length = 20;
input nK = 1.5;
input nBB = 2.0;
input alertLine = 1.0;

def sqzHist = TTM_Squeeze(price, length, nK, nBB, alertLine).Histogram;

plot cyanToBlue = sqzHist > 0 and sqzHist < sqzHist[1] and sqzHist[1] > sqzHist[2];

plot redToYellow = sqzHist <= 0 and sqzHist > sqzHist[1] and sqzHist[1] < sqzHist[2];

Alert(cyanToBlue, “TTM Squeeze Blue Bar”, Alert.BAR, Sound.Ring);
Alert(redToYellow, “TTM Squeeze Yellow Bar”, Alert.BAR, Sound.Ring);

Hi Pete,

Since I’m new to ToS, I just wanted to inquire if

1) the code above should be inserted into a new study and then would be added to a chart and
2) Will this audible alert only be triggered on a displayed chart or can it be applied to a watchlist that uses the TTMSqueeze script you developed (but using a 5 min interval)

Thanks!

This is only applicable to chart studies. So the answer to question 1 is yes. Question 2, this code will only trigger an alert on an active chart. Alerts cannot be applied to a watchlist. However it is possible to create a custom scan and use that to build a dynamic alert that is applied to a list of stocks. We explain how to create dynamic alerts from custom scans towards the end of this video: https://www.hahn-tech.com/thinkorswim-overnight-range-scan-alert/
If you require further assistance please post a new question in the forum.

No, the languages are quite different so you could not copy and paste this code to TradingView and get it to work. The other reason is that this code makes use of a proprietary study licensed by John Carter. Thinkorswim allows us to make use of the licensed study without exposing the proprietary source code.
