Volume Shelves — Support & Resistance
Trend Edge identifies volume shelves: price zones where historically elevated trading volume
creates structural support or resistance. A volume shelf forms when a disproportionate share of cumulative
volume was transacted at a specific price level, making it a high-conviction anchor for future price reactions.
Trend Edge's AI Consult feature delivers a comprehensive, multi-layer trade plan for Prothena Corporation plc
(PRTA) powered by Claude Opus — Anthropic's most capable AI model.
The analysis covers five layers:
technical analysis (near-term, medium-term, cyclical, and secular trend, momentum,
volume shelf support and resistance, breakout and breakdown signals),
qualitative analysis (business model, competitive moat, sector dynamics),
insider sentiment (buy and sell signals from executive and director transactions),
share stats analysis (institutional accumulation, fund positioning, short float squeeze potential), and
fundamental analysis (valuation, revenue growth, profit margin, earnings quality).
AI Consult synthesizes all five layers into a single bullish or bearish thesis with explicit entry, exit,
stop loss, and take profit levels — giving you a complete, AI-powered trade plan with defined risk/reward.
Whether you are building a long position, initiating a short, or looking for a reversal setup,
AI Consult identifies the highest-probability signal from the current trend.
