Is there a way to search or draw broadening fomrations or mega phone patterns in TC2000

I'm sure there are better ways to do this, but my first thought would be to just count the number of wider bars in a row and use it as a sort in TC2000 v17.

TrueInRow(H - L > H1 - L1, 20)

One basic flaw in this technique is that you might consider the pattern to be widening based on the tops and bottoms of multiple bars instead of single bars. If so, you might want to check for that by changing the time frame to something longer or by altering the formula a bit.

TrueInRow(MAXH3 - MINL3 > MAXH3.2 - MINL3.2, 20)

You can alter both the number of bars for each period (the 3s) and the number of bars to skip between checks (the .2s).

Another possible flaw would be if you want to require some sort of outside bar type situation where the range not only got bigger, but that the range of all of the previous bars in the pattern were inside the widening range. This is more complicated.

We can test for this for bar to bar fairly simply.

TrueInRow(H > H1 AND L1 > L, 20)

And can even do the same sort of thing for the other formula.

TrueInRow(MAXH3 > MAXH3.2 AND MINL3.2 > MINL3, 20)

But this would not check for all of the previous bars being inside the current range as the range could be going in an upward or downward slope which leaves the early bars outside the new range while still getting counted. I can't think of a simple obvious way around the issue if you actually wanted to avoid this type of pattern.
