The channel has as its center a 7 cycles , when the average line (Called Signal, the purple one) crosses the upper band it is time to make a Long.
If it crosses the lower band it is time to make a short, if the line returns to the channel a signal appears to close the operation.
The indicator works with all timeframes, I use it on the 1 hour chart and I do the trades in 1 minute.
