This indicator is perfect for scalping in 1 minute, it consists of a channel and a line that is made up of the average of the highs and lows of the price in 12 and 64 cycles. The channel has as its center a 7 cycles SMA, 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.
