I have been using the draw line feature to help set up trade opportunities visually.  For trading the e-mini a percent value of 0.135 creates a channel that equals two points.  I set the upper blue line at the stop level I would use in a trade.  I set the price in my online order ticket to the value of the red line.  Then I have a picture of my stop and reward to risk ratio on screen when I make a reject/not-reject decision.  A one to one ratio is not good, so I am looking for an entry that has a reasonable chance of not being stopped out, and that has better downside potential than the lower blue line.

This is a tactical tool that I am experimenting with as I am learning to trade.  It is not a trade recommendation.  It is an idea that someone may be able to use or improve.

I move this line up and down continually as I follow the market action, and keep the price in the ticket equal to the level of the line on the chart to help prevent entering on the wrong side of the trade.
