[Forex Trader]

plot two moving average, for example, ma(100) and ma(200),
if Close>max(ma(100),ma(200)),set the bar color to Red, if Close<min(ma(100),ma(200)),set the bar color to Blue. and if the close between max(ma(100),ma(200)) and min(ma(100),ma(200)), set the bar color to the same as the previouse bar.
