Adding one more condition to efs

[escript]

Hello ,

How can i add the following one more condition to the attached efs . The efs defines big candlestick bars .

Additional condition : the big candle stick bar (black bar ) : high is less than or equal to lower keltner channel (50,2.5)

(white bar ) : low is greater than or equal to keltner channel (50,2.5)


Thanks
