Bear Flag (FTSE 100) UKX - And Hopefully Not A Triangle!?

There are many suggestions that we're seeing an ascending triangle (with a confirmed breakout) on the UKX.
The white horizontal line shows the resistance of the Triangle.
Something just didn't feel right for me on that pattern - particularly the 'breakout' which seemed muted and weak considering this multi-week build up.

Instead I'm suggest a bearish flag in blue, which is more common in bear markets.
If correct - that would suggest an aggressive move to the downside, way below the support, in the coming week.

For now I'm holding onto my short.
Keen to hear your thoughts!
