The decline of volume and VMA confirms the overall downtrend since january 2018. VMA is declining mostly and rarely stalling, the volume bars mostly didn't even get close to VMA. So basically the downtrend gets confirmed just by looking at the volume. This very simple indicator should not be underrated. The bull runs we saw in april and july were backed up by slightly higher volumes which is indicated by volume bars being slightly higher. Nevertheless this had no sustained impact on VMA.

As you can see the oscillator is below zero since end of march/beginning of april. This is just a visualized confirmation for declining volume. Please ignore the last datapoint, the week has just begun.

The zone is composed of the lowest price of 11/06/2017 (5400) and the opening price of 11/13/2017 (5810). I call the zone boundaries "early support" (upper) and "ultimate support" (lower). Instead of a support zone some TAs use a support level which is near or inside the upper level of my support zone. That's totally legit but only a part of the truth. When we look at the candle from 06/18/2018 we can see that 5800 was pierced (maybe not on every exchange, i haven't checked that) but the price immediately reversed above it. This is an indication that the low of 06/18/2018 didn't trigger any, any more or not enough sells for a further price drop. The support zone is quite dangerous because prices within that zone will trigger sells for professional traders and algorithm trading bots (sometimes referred as "algo bots" or just "bots"). Opening short or long positions will surely have an impact on the price too but i'm gonna ignore that here to keep it simple. Since no one knows the selling parameters of professional traders and bots, the danger within the support zone raises exponentially after breaking the level of "early support" and as closer the price comes to the level of "ultimate support". It's not a question whether sells COULD be triggered, they WILL according to the selling-parameters. We just don't know at which levels the house of cards will start to collapse. Once the price doesn't stop declining and the selling volume exceeds a "critical mass", anyone who hasn't sold already will follow, driven by fear, lost confidence, doubts, uncertainty or plain panic. According to Andre Kostolany psychology is one of the main factors that drives financial markets (and by the way, he also invented the term "weak hands"). Once the house of card has collapsed, we will see hyper-accelerated sells (panic sells) until they get slowed down/stopped by buyers stepping in. The support zone/level might be lost by then (who knows?) and will become the next mayor overhead resistance to break.

Because there is a correlation between volume and price it's remarkable that the support zone still holds. We're in a clear downtrend which should print lower highs and lower lows. While we see lower highs, we don't really see lower lows. Well, we can see them if we ignore the wicks and consider them as "noise". The support zone holds everytime we come close to or even pierce it. I've seen some TAs with supersized bullish triangles composed of a horizontal level near or inside the support zone (some TAs use a downtrend which ignores a or some wicks being "noise" instead of a horizontal level) as the bottom and one of the downtrends as upper resistance. This might be legit, no one knows, but you shouldn't expect a bull run driven by a bullish wedge (or similar) where price gets squeezed by support and resistance or even earlier. Why? This clearly is IMPOSSIBLE without fresh money flowing into the market (=market cap rising) followed by a sustained rise of volume.
