Drawing a trend channel from support/resistance rather than drawing it from the mid-line.
By starting a trend channel off of the desired resistance or support; you know the channel is exactly where it should be. I find that from there it is easy to find the channel and a mid-line naturally falls in place by being a 50% data input and low and behold it is always in the perfect spot according to the price action.
When drawing from the mid-line first it creates a lot of extra work trying to adjust each end of the channel and move the channel where it should be. Angles can be off, you have to drag and move the channel over and over to get it right and the top and bottom lines are very finicky when adjusting to the desired spot.
**Another cool option would be being able to copy/duplicate drawn lines so you have a clone of a line drawn at support or resistance to be able to form a channel. And from there to take it further you can add a 50% data input to be your mid-line.
