What Trend meansA trend-following algo. BUY while an uptrend holds on that horizon, EXIT when it breaks. Long only, judged on daily, weekly and monthly candles.
What Rebound meansA dip-buying algo. BUY after a sharp short-term drop in an otherwise healthy stock, EXIT once price closes back above its 12-day average. Short term and Mid term profiles.
What Patterns meansA chart-shape detector. Finds wedges, double tops and bottoms, cup and handle and more, marks the breakout or breakdown and measures the textbook price target. Full method
