The markets have been rising since February, with huge, unprecedented volumes. We all know that prices change hour to hour and day to day, but these have to be set against the wider trend. A 1% price drop in an hour means nothing against a rise of 5% over the day, or a drop of 5% over a day means nothing agianst a rise of 25% for the week.
So the cause of the latest wave of green across the market is just that a) the markets are bullish, and b) prices have been stagnant for a couple of days. So with the high volumes a breakout was going to happen, and with the market being bullish, upwards was the likely direction.
I much prefer this sort of rise punctuated by periods of stability to the sort of relentless rise we saw in 2017. If the prices stay level for a while, it helps to establish support and recognition that the price is justified, rather than it just being an artificial inflation due to runaway FOMO.
