LONG COPPER @ 2.15 -2.16 for next bull wave

Ok, my first idea, so please excuse the very basic chart here!!. Copper has been selling off daily from its rally high of 2.3...calculating from the beginning of last rally we are approaching a crucial 61.8 retracement level around 2.150, also at current price we are at 0.382 retracement level from its bottom, as copper now appears in established 'bull' territory it might be worth going long around 2.15-2.16 if price action and RSI are supportive, check 4h/daily charts for confirmation....feel free to tear me apart guys, its all learning for me at this stage!!! I've even put my real name on here , or is it?
