Electronic trading is growing in the FX market, and algorithmic trading is becoming much more common. There is much confusion about the technique.

The empty (transparent) candles show increase, while the dark (full) ones show decrease. The length of the body shows the range between opening and closing, while the whole candle (including top and bottom wicks) show the whole range of trading prices for the selected time unit.

Over 95% of the market activity is for speculative purposes, so there is no intention on either side to actually perform the contract (the physical delivery of the currencies).
