Well am actually good at reading candle sticks as a result of reading a lot of books and watching videos .. you should try it out some time..
green candle means buyers(bull) are in the market so the prices opens in a position down and closes in a position up were the buyers have leave the market. because when buyers are in the market, the willingness to buy and demand increases and so it drives the price up
red candle means sellers(bears) are in the market so the prices opens in a position up and closes in a position down were the sellers have leave the market because when sellers are in the market, the willingness to sell and supply increases and so it pushes the price down
so what happened there is that when the buyers had left the market indicated by the closure of the green candle, the seller came in but the sellers were willing to sell at a price much lower than the last price at which the said coin was being bought. so it resulted in red can candle opening up as usual but a little bit down from where the green candle closed up...
hope that answered your questions ...
