I would describe this as an upwards channel with a symmetrical triangle inside of it.
The pink resistance trendline is now valid due to there being 3 points on it, and the blue on has even more - therefore I consider this formation valid until broken. It is indeed the break of either the pink or blue trendlines that I will be trading.
A break of the pink resistance trendline can see price up at previous highs of 88, while a break of the blue support trendline can see price at the most recent lows of 84.
