HOW IT WORKS
Enter. Analyze.
Understand.
Ridgewell is not a black box. Every filter runs real math on real market data. The only thing AI generates is the plain-English coaching summary — everything else is calculated, not guessed.
Enter any US-listed ticker
Type in any stock or ETF symbol — SPY, AAPL, NVDA, TSLA, anything listed on a US exchange with at least 10 trading days of history. You're analyzing the underlying stock, not an options contract directly.
Data source: Yahoo Finance end-of-day feeds, updated after market close each trading day.
14 independent filters run automatically
Each filter targets a specific failure mode that causes retail traders to lose money. They run independently — no single score, no black box algorithm. Every result is shown, every pass or fail is explained.
MARKET CONDITIONS
SPY REGIME
Is the broader market in a tradeable trend?
Compares SPY's current price to its 20-day and 50-day moving averages. If SPY is below both MAs, market conditions are unfavorable for aggressive long setups. This single filter eliminates most losing trades taken against the trend.
VIX LEVEL
Is volatility too extreme to trade safely?
Reads the VIX fear index. Above 30 signals panic conditions where options premiums are inflated and directional moves are unreliable. The filter flags elevated VIX so you can size down or sit out.
SECTOR TREND
Is the sector supporting or fighting the setup?
Checks the relevant SPDR sector ETF (XLK, XLF, XLY, etc.) against its own 20-day MA. A stock trying to break out while its entire sector is declining has a significantly lower probability of follow-through.
TREND STRUCTURE
MA20 / MA50 ALIGNMENT
Is price in a confirmed trend?
Requires price to be above MA20, and MA20 to be above MA50 for bullish setups (reversed for bearish). This three-layer check filters out stocks in choppy, sideways conditions where options strategies bleed value.
SUPPORT / RESISTANCE TOUCHES
Has this level been tested and respected?
Counts how many times price has bounced off a key level in the past 20 sessions. Levels tested 2+ times carry more technical significance. A first touch is speculation; a repeated bounce is evidence.
FALSE BREAKOUT CHECK
Did price actually commit to the move?
Measures where price closed within its daily range. A close in the bottom 30% of the day's range on a supposed breakout is a rejection signal — real breakouts close near the high of the range.
MOMENTUM
VOLUME (1.5× AVERAGE)
Are real buyers or sellers showing up?
Compares today's volume to the 20-day average. Moves on below-average volume are weak and often reverse. The 1.5× threshold filters out noise and requires meaningful participation before flagging a setup.
OBV CONFIRMATION
Is cumulative volume backing the price direction?
On-Balance Volume adds volume on up-days and subtracts it on down-days. When price rises but OBV falls, fewer real buyers are participating — a divergence that precedes reversals more often than not.
RELATIVE STRENGTH VS SPY
Is this stock outperforming the market?
Compares the stock's 10-day return to SPY's 10-day return. Stocks that are already outperforming their benchmark are more likely to continue leading. Lagging stocks rarely become leaders mid-move.
GAP %
Has the move already played out overnight?
Gaps larger than 2% at open often represent exhausted moves — traders who bought the news overnight. The filter rejects setups where the potential edge has already been priced in before the market opened.
CANDLE QUALITY
Does the most recent candle show conviction?
Analyzes the candle body-to-wick ratio. Long wicks relative to the body signal indecision or rejection. A quality candle closes in the direction of the intended trade with minimal upper shadow (for longs) or lower shadow (for shorts).
RISK
ATR STOP DISTANCE
Is the required stop loss actually manageable?
Calculates the Average True Range over 14 days and checks whether a 1.5× ATR stop would require risking more than your defined maximum per trade. If the stop is too wide for your account size, the setup is filtered out.
BREAK-EVEN RULE
Does this trade have room to be profitable?
Options have a break-even price that accounts for the premium paid. The filter checks whether the underlying has enough room to reach break-even before the stop is hit. Trades with unfavorable break-even ratios are flagged.
MARKET BREADTH
Is broader momentum helping or fighting this setup?
10-day price return identifies whether the stock is approaching overextension. Setups in stocks that have already moved 15%+ in 10 days carry significantly higher reversal risk — the filter catches these before you enter.
One AI-generated coaching summary
After the 14 filters run, Ridgewell passes the results to an AI coaching layer that explains what they mean in plain English. Not "OBV divergence detected" — but "volume has been shrinking while price moves up, which often means fewer people are actually backing this rally."
IMPORTANT
The coaching summary is the only part of Ridgewell that uses AI. The 14 filters, the trade levels, the stop loss, the position size, and the pass/fail results are all calculated mathematically from real price and volume data — not generated by a language model.
The coaching also references your personal trade history. After you log trades, Ridgewell identifies your patterns — which filters you ignore before losses, which setups your win rate is highest on — and surfaces those in every new analysis.
Log it as a paper trade
After any analysis, log the setup as a paper trade with one tap. No real money involved. When the trade closes, mark it won or lost. Your win rate, trade history, and performance metrics build automatically over time.
The paper trade tracker exists for one reason: to let you verify that the system actually works before you put real capital behind it. Most trading tools skip this step. Ridgewell doesn't.
