TTM Squeeze scan 2nd blue bar after 2 or more cyan

Update: There is a newer version of this type of scan which enables you to select any number of consecutive bars and any combination of colors. You will find that solution posted here:

First order of business is to provide a link to that previous post you referenced:

Please realize that if you mention a previous post without providing a link to you will be frustrating a very large segment of our audience.

Seems I have created a monster. How many different combinations of different colored bars do you suppose folks will think of? And each one requires a custom solution. If I thought it was popular enough, I might consider building a premium scan for this that allows a full range of flexibility for selecting various combinations of different colored bars by adjusting some simple user inputs at the top if the code. But I don't see a need yet.

Bars on the TTM Squeeze histogram are colored according the to the following very simple rules:

1. Cyan: higher than previous bar and above zero
2. Blue: lower than previous and above zero
3. Red: lower than previous and below zero
4. Yellow: higher than previous and below zero

So we take the code you copied from the previous post and substitute the rules for blue and cyan. I have retained the previous lines of code so that this solution contains all four colors. There are two scan signals. One for the original that was provided in the previous. The new one has been added for this current request.

input price = CLOSE;
input length = 20;
input nK = 1.5;
input nBB = 2.0;
input alertLine = 1.0;
def hist = TTM_Squeeze(price, length, nK, nBB, alertLine).Histogram;
def histCyan = hist > 0 and hist > hist[1];
def histBlue = hist > 0 and hist < hist[1];
def histRed = hist < 0 and hist < hist[1];
def histYellow = hist < 0 and hist > hist[1];
# use this to scan for second yellow bar after two or more consecutive red
#plot scan = histYellow and histYellow[1] and histRed[2] and histRed[3];
# use this to scan for second blue bar after 2 or more consecutive cyan
plot scan = histBlue and histBlue[1] and histCyan[2] and histCyan[3];
