Oscillators are designed to signal a possible trend reversal. They can act as alerts and should be taken in conjunction with other technical analysis tools. Oscillators can be used to confirm other technical signals. Use the following link to access Lane's Stochastic help.

The daily MACD line is above its signal line since February 10, 2026. This is an indication that the short-term trend is up. The distance between MACD and the signal line is low and getting smaller. It indicates that the current short-term uptrend is getting weak.

During the last week, the price has fallen below the Parabolic SAR (stop and reversal). A Parabolic SAR above the price is a bearish signal, and it indicates that momentum is likely to remain in the downward direction. A Parabolic SAR is used as a trailing stop loss for long or short positions. It works best during strong trending periods.
