BLNK,What is the RSI and Volume both telling us?

BLNK is already on an uptrend. Recently price has been in somewhat of a sideways move, Still making higher highs and higher lows (uptrend). I noticed a pattern where volume contracts and RSI contracting right before another leg up to make another new High. Where price currently is, we see another contraction with volume and RSI. As far as market structure, We are at an intermediate resistance level, I would wait for some kind of chart/candlestick pattern for a long confirmation. Overall this is looking like nice swing trade to the upside, or some $58 calls.
