This is one of my invented 15 minutes scalping method whenever I find the “Ascending Channel”

As you can see in the chart the point where price touches the resistance level of the channel (red arrow) is where to place a short or sell. While the point support level (green arrow) is the buy or long zone.

This point are not just picked randomly, they are selected based on the following criteria

1. the initial resistance becomes support.
2. the levels at which resistance becomes support have equal distance in between.
