SPX / H4 : The first 2018's swing battle may have begun !

I think we may have reached the point where volume will start to pile up in a narrow area, crushing up momentum as volatility will slowly pick up before a nice burst occurs.
This burst will of course have both positive and negative outcome possibilities.. Positive outcome will very likely sign the entry in a very agressive bubble trading mode before krashing up the speculative phase.
Negative outcome will probably cause a little "sell off" session with investors massively reducing leverage after being too confidently exposed to equities.
Trend remains bullish so there's no point searching this top for a bear marker reversal.. !

Hope this idea will inspire some of you !
