# 3. Positive Delta Volume USDT Moving

#### What is a positive delta?

This is the difference between the volume on sale and purchase, in which purchases prevail over sales. That is, for a certain volume, there were more market purchases than sales.

{% hint style="info" %}
Please note that the delta growth from 200K to 500K will be +150%, and this is essentially one large purchase of 300K, but if the same large purchase occurs when the delta was 40K, the growth will be 750%
