Copper / XCUUSD / CU - Preparing for bullish buy signal

Copper has taken off from a nice bullish pin bar that had formed off of a key support trend line. This was a near text-book pin bar setups and the types of setups price actions traders should always be watching for. Price blasted off higher from the pin bar and is finally having a little bit of pause from a key resistance zone. When I will be watching for is for price to either fall back to the same support trend line and for another buy signal to form, or if price breaks through key resistance I will then be watching for a pullback to this level (which would have become a support zone) and then watching for any price action candlestick buy signals to form.
