Inspired by Mark Minervini's sell rules in "Think and Trade Like a Champion".

- Stock Up 3% or More: Flags when the stock is up 3% or more on the day.
- Inside Day Condition: Checks if the current day's high is lower than the previous day's high and the current day's low is higher than the previous day's low.
- Close Below 50-day SMA: Indicates a negative confirmation when the stock closes below the 50-day Simple Moving Average (SMA).
- Weak Close Condition: Similar to the Upper 50% Range Condition, but looking for lower closes.

- Three Lower Lows: Identifies a pattern where the current close is lower than the previous two closes.
