1,000 Sells followed by .1 Buys. Candle is fucking GREEN. Perhaps I do not have the EXACT method by which they fuck this up, but I DO know it is fucked up- Uhm kAy?
It is pretty simple. I will give you an example. Lets say, at 16:01 someone makes the first sell into the highest bid of 0.0039, the opening price of the 16:00-16:05 candle is 0.0039. After that, someone dumps it to 0.0037. If then the last trade in that range on say 16:04, is to buy at the current highest ask of 0.00395, you will get an opening price of 0.0039, a low of 0.0037 (shadow), a high of 0.00395 and thus a green candle.
EDIT: To add, some people use the low liquidity and low trade volume to manipulate this candles (making them green, so it looks more bullish).
