There are four 'weight' settings available in Trendline Pro that allow you to fine-tune the trendline selection process. These are Length Weighting, Touchpoint Weighting, Gap Weighting and Proximity Weighting. By default, all of these weightings are set to 1. If you assign a larger number to one or more of the weighting parameters, you are instructing the indicator to create an internal bias towards a particular trendline characteristic. For example, if you set Touchpoint Weighting to 2 and leave all of the other weightings at the default value of 1, the indicator will favor those trendlines that have the most touchpoints when it determines which are the best trendlines to display on the chart.
•Length Weighting: Use the Length Weighting parameter to instruct the indicator to favor longer trendlines over shorter trendlines. Range is from 1 to 20 with 1 being the default value.
•Touchpoint Weighting: Use the Touchpoint Weighting parameter to instruct the indicator to favor trendlines with more touchpoints over trendlines with fewer touchpoints. Range is from 1 to 20 with 1 being the default value.
•Gap Weighting: Use the Gap Weighting parameter to instruct the indicator to favor trendlines with smaller gaps over those trendlines with larger gaps. A "gap" is simply the distance between touchpoints on a trendline and the theory is that a trendline with evenly distributed touchpoints is more robust than a trendline comprised of touchpoints that are perhaps clustered at either end of the trendline. Range is from 1 to 20 with 1 being the default value.
•Proximity Weighting: Use the Proximity Weighting parameter to instruct the indicator to favor trendlines that are closer to the current price action. Range is from 1 to 20 with 1 being the default value.
Note: The 'best' Upper Trendline and Lower Trendline will always be displayed as a slightly thicker line than any other trendlines that may be displayed on the chart.
