Silver is probing a key downtrend line that has been in tact since mid 2017. In addition, there is the 161% Fibonacci extension of the last move lower at 15.98. Horizontal resistance which was support from 2018 also comes in around the $16 level. The current bull flag pattern points to 16.19, and if that completes, these key technical hurdles would be cleared. That would be a strong case for a long term bullish run over time.
