t is easiest to illustrate what a Weak or Poor Low by discussing what a Strong or Excess Low is. When the market moves lower and finds that prices are just too low to be fair, the traders generally immediately drive price higher as buyers grab up as many contracts as possible at the perceived low prices. This generally leaves a buying tail on the chart and little in the way of volume on the profile.
A Weak or Poor Low is the opposite. This occurs when the market tests a low and can’t move away from it readily. A lot of volume trades a tick or so from the low print and buyers don’t seem to be interested in lifting prices higher. This is a weak or poor low and there is a generally tendency to revisit that low within that session or immediately after that session.
