Bull Flag and Bear Flag Formations for ThinkorSwim

I have this bull flag indicator I pulled from the post here: https://usethinkscript.com/threads/bull-flag-and-bear-flag-formations-for-thinkorswim.467/

I modified it to work for day traders. I use this indicator while showing the 1 MIN chart, but its aggregation is on the 3 min chart. So I can see ALL bull flag formations on the 3 minute charts, at the 1 min chart level.

HOW TO:
  1. Add the script to your 1 min chart.
  2. ONLY use this on a moving upward trend. I use a 20 chart layout, opening this up with Trade Ideas scanners. I find the Momentum stocks that are continuing to hit new highs. The problem with these stocks, is you never know when they will crash, right? So now you know, when they will push up.
  3. When I place these upward trend charts and this indicator finds a bull flag, it sends me a PING. I look at the chart and I have about 30 seconds - 5 minutes to decide if I will enter the trade.
    1. If its a flag sideways bull flag, I have longer to decide. If its a moving upwards bull flag, I have 30 seconds or so to decide to enter the trade.
  4. I kid you not, 9 times out of 10 bull flags that appear, this one makes money on UPWARD trending stocks 90% of the time.
This is one of my favorite indicators as it makes money ALL day long when paired with a momentum trending up scanner.

I added it to my 1 min chart but I'm confused as to what is supposed to happen, I know today is probably a bad day cause everything's red but can you maybe post a screenshot or something showing how its supposed to alert and how it looks on chart @spoiledtechie

Any one know how to setup a scanner for Bullish Pennant & Falling Wedge
Click to expand...
Have you looked at the Patterns available for Scans...??? Add Filter > Patterns and de-select the ones you don't want to use... Bullish Pennant isn't in the list so you might need to create it using the Pattern Editor... I'll leave it to you to research further in the Learning Center...

Do you know how to add the pattern ?

I have never done it but I know it is covered in the Learning Center, hence my pointing you there... No need in my learning something I'm not interested in just so I can explain it to you...
 
This one draws the diagonal lines and tell how many candles are in the wedge
