CHART — Rebuilt from the ground up The trading chart is a completely new engine. Gone is the Apple Charts line graph. In its place: a native Canvas renderer built the same way professional platforms render charts — direct GPU draw calls, one pass per frame. What you get: • Real OHLCV candlesticks — green and red bodies with proper wicks from high to low. You can now read momentum, indecision, and conviction directly from the candle shape. • Volume bars — trade activity for each period shown as proportional bars below the price area. More trades, taller bar. • EMA 9 (gold) and EMA 21 (purple) — exponential moving averages drawn as smooth lines over the price. They appear automatically when you have enough candles. • Momentum scrolling — flick the chart and it keeps moving with natural deceleration, the same physics as iOS native scroll. • Crosshair with axis bubbles — when you scrub a candle, a price bubble locks to the right axis and a date bubble locks to the bottom axis. No more guessing where you are. • Current price line — a dashed line marks where your equity sits right now, with a live badge on the Y axis. • Gesture corrections — X-axis zoom and Y-axis zoom now move in the direction you expect. Drag right to see more candles, drag up on the price axis to widen the range. • Day/Week/Month P&L — the delta in the header now correctly updates when you switch between timeframes. When in Week or Month view, a "Today" line shows today's daily change at a glance. ZEN AI — Fixed and unified Zen was returning identical responses to different questions. Root cause: the iOS request was timing out at 30 seconds while the AI model (o4-mini) needs up to 45 seconds to reason through your data. Every request was silently falling back to a generic local response instead of reaching the server. Timeout is now 90 seconds. Zen sends real analysis every time. The "Prepare with Zen" and "Train the leak" were two separate entry points to the same AI — creating confusion about which one to tap. They are now unified into a single button. When your Zen Mirror has enough data, the button opens Zen with full context: your active behavioral leak, the money impact, the evidence, and the rule to protect — but without forcing a specific mode. If you want to prepare mentally, Zen prepares you. If you want to run practice scenarios, ask for them. One button, full range. PERFORMANCE Home screen metrics (win rate, equity curve, daily P&L) now compute once when your trades change and cache the result. Previously they recalculated on every SwiftUI render pass. The Stories progress bar timer dropped from 5 frames per second to 2 fps — visually identical, 60% less CPU work.
