📉 Trend Dampening

What's new

Retrend now supports Trend Dampening, so a recent sales trend doesn't push your forecast in the same direction forever — its influence fades over time and the forecast eases back toward your original plan.

What you can do

Control how long a trend sticks around
– Set a Grace Window to keep the retrend effect at full strength for a set number of weeks before it starts to fade.
Choose how the fade happens
– Pick Exponential dampening (fades faster at first, then levels off — tune the speed with Half-life) or Linear dampening (fades at a steady, constant rate).
Set when it fully resets
– Use Horizon to define how many weeks out the forecast fully returns to your original, original forecast.
Apply it broadly or case-by-case
– Turn on Trend Dampening globally so it applies to every choice, or enable it for a single choice in the Assortment Plan when it needs its own settings.
Preview the effect before committing
– See how your Grace Window, Dampening Style, Half-life, and Horizon settings shape the forecast right in the configuration window before you save.

Why it helps

Keeps a short-term spike or dip from permanently skewing your forecast for the rest of the season.
Gives you control over how quickly you trust a new trend versus your original plan.
Lets you fine-tune dampening for specific choices that behave differently from the rest of your assortment.
