From June to now on the 1D chart, AMC has very slowly been creating Lower High's and Lower Low's but alongside that the Volume has also been decreasing which can be interpreted as a signal for a bullish reversal - volume typically follows strong trends.
With that being said, using ADX to analyse the trend strength (below is the value interpretation sheet), we are seeing that our slow downtrend since June has been a very weak trend as it is sitting well below 25, 25 being the start of a strong trend. More importantly, our recent free fall down actually caused our ADX to also spike down which to me indicated a positive short term divergence.
From that, the OBV is showing a bullish divergence as it has been consistently rising while the price is falling which could be an indication of a potential bullish reversal to come.
