Someone pointed out that when buying within that box where there is an obvious support -one should never buy on that area but instead plot a fibonacci and enter on that 1.618 and expect an upward movement. I don't how true it is but let's see.
An update from
The yellow line is a strong support formed on July 13 and retested. Trend is still down but as long as it holds above the yellow line there is still a recognizable pattern or else it will touch the red line. Looking forward for the price to break upward the pitchfork.
