If you look carefully you can see the small magenta squares which indicate the coordinates I used to draw a channel. When I drew the channel directly over the Andrews Pitchfork I was careful to stay within the the past five days.
The two heavy horizontal lines were drawn while viewing the chart in a 5 day 5 minute mode. These lines demonstrate the limits of the 5 day 5 minute chart so that the channel will be correctly drawn within the last five days.
The chart below is now back in the 5 day 5 minute mode. As you can see the Andrews Pitchfork which was drawn with a starting point more than 5 days ago is no longer accurately depicted.
This method of redrawing lines on your charts is a lot of extra work, but it is the only way to maintain accuracy of any drawing whether it be a trend line or fork. As you can see below the Andrews Pitchfork has moved a significant distance. Basically it has become useless garbage..
I brought this error to the attention of ThinkOrSwim well over a year ago but the problem persists...
Here's one more example. The true fork is yellow. The blue fork is ToSWhat do you think? Would this make a difference in how you you would trade... Yeah me too.
