EDRY Just Showed Why Sell Rules Matter
EDRY fell 20.44% today on roughly 2.5× relative volume. After a powerful advance that largely followed the 10-day moving average, the stock delivered a clear change in character.
The first warning was the gap below the 10-day. Selling continued through much of the morning, and price then broke through the 20-day. In MTS Velocity, RVOL Now was already flagging elevated volume early in the session, giving us another reason to pay attention.
An alert near your planned exit level brings the stock front and center. Your sell rules determine what you do next. If you caught the earlier breakout, an orderly exit could still leave you with a substantial profit, even after giving back some of the advance.
Unfortunately, catching a big winner doesn’t automatically make someone good at managing it. Without sell rules, it’s easy to keep finding reasons to hold: the earnings still look great, the industry is strong, or the stock will probably bounce. Meanwhile, a meaningful gain starts disappearing.
Kullamägi’s approach is relevant here. His published breakout rules include taking partial profits after the initial burst and trailing the remaining shares with the 10-day or 20-day moving average, using a closing break of the selected average as the exit signal. EDRY finished below both today.
For a swing trader following a similar approach, this is a textbook sell signal. Other traders may have acted earlier under rules for a sharp, heavy-volume breakdown. The important thing is having those rules established before the selling starts.
And if EDRY rebounds tomorrow or reaches new highs again? That wouldn’t invalidate a disciplined exit based on today’s evidence. You evaluate a trading process across many trades, and protecting gains sometimes means leaving before a stock’s final advance.
Sell rules exist because you cannot know which breakdown will recover and which will become a much larger decline.
A single unmanaged position can undo months of good trading. You don’t need to capture the exact top, but you do need to know when your plan says the trade is over.
