How signals are generated โ two layers
Every BUY/HOLD/SELL call passes through two independent checks before you see it:
- JEV AI Engine โ Analyzes price action, volume, momentum, and market context to output a direction call with a confidence percentage (0โ100%) and a probability score. It's trained to be selective โ HOLD is the most common output (~55% of the time) because high-conviction setups are rare.
- Technical Indicator Cross-Check โ Five indicators run independently: SMA 20/50 trend, MACD, RSI, Bollinger Bands, and Stochastic Oscillator. Each casts one vote, and a consensus is flagged when 3 or more of the 5 agree. When they disagree, confidence drops and the risk engine may block the trade.
DIOVRA's indicators are momentum and mean-reversion tools. They can disagree with other methodologies (e.g., trend-ribbon systems like Guppy/GMMA) โ especially in choppy markets. That's normal: DIOVRA is one perspective, not a replacement for your own analysis.
JEV Decision Engine
- Choice โ BUY/HOLD/SELL with confidence.
- Noul โ Yes/No probability.
- Score โ Poor to Excellent.
- Confidence โ 0โ100% certainty; your Confidence Threshold filters calls below it.
Risk Engine
Every order is checked before it fills: max $5k per position, $20k portfolio cap, 25% single-stock limit, 5% ATR volatility guard, max 6 open positions, and low-confidence signals blocked. If losses spike, an automatic emergency stop halts all trading so a bad day can't become a catastrophic one โ a last-resort circuit breaker, not a button you need to find. Options orders also carry an advisory confidence warning.
Paper Trading โ Stocks & Options
Virtual $10k shared across both. Analyze โ Paper BUY/SELL at the last price. On the Options tab, call/put chains show Greeks, breakevens and probability before you place a long-only order. No real money, ever.
Key Concepts
Confidence Threshold (CT)
Slider on Trade page sets minimum direction probability. If JEV says BUY at 47% and CT is 75%, trading is disabled. CT filters weak signals. Default: 70%. Higher = fewer but stronger trades. Two numbers: DIR% = chance direction is right. CONF% = JEV certainty in analysis.
Algorithm Consensus
The five indicators โ SMA trend, MACD, RSI, Bollinger and Stochastic โ each cast one vote. When 3 or more of the 5 agree, DIOVRA highlights a consensus. Consensus + high JEV confidence = strongest signal.
Risk Engine
DIOVRA blocks trades that exceed safety limits: max $5k/position, 25% single stock, 5% ATR, 6 open positions. You cannot override these.
Trade Journal
After each paper trade, log WHY you took it. Review your journal weekly. Patterns emerge: you'll see which signals you trust and which you second-guess.
Win Streak
Track your winning and losing streaks. If you hit 5+ wins, you're building discipline. If you hit 5+ losses, review your journal โ the system works, the execution may not.
Paper vs Real
DIOVRA is paper trading only. No live execution. If you want to trade real money, use a separate brokerage. DIOVRA shows you what to trade, not how to execute.
RSI โ Relative Strength Index
Momentum oscillator (0-100). Above 70 = overbought (potential sell), below 30 = oversold (potential buy).
SMA โ Simple Moving Average
Average price over N days. SMA20 crossing above SMA50 = bullish. SMA20 crossing below SMA50 = bearish.
EMA โ Exponential Moving Average
Like SMA but weights recent prices more heavily. Reacts faster to price changes.
ATR โ Average True Range
Measures volatility. Higher ATR = more price movement = wider stop-loss needed.
MACD โ Moving Average Convergence Divergence
Trend momentum indicator. MACD line crossing above signal line = BUY signal.
Bollinger Bands โ Bollinger Bands (20, 2ฯ)
Price channel. Price near lower band = potential BUY (oversold). Price near upper band = potential SELL (overbought).
Stochastic โ Stochastic Oscillator
Compares close to price range. Below 20 = oversold. Above 80 = overbought. K crossing above D = BUY.
relVol โ Relative Volume
Today's volume projected to a full session, compared against the 20-session average. During market hours only part of the day has traded, so DIOVRA projects the pace forward โ without that the figure reads about half its true value until the close. relVol > 1 = above average interest. High relVol confirms breakouts.
JEV โ JEV Decision Engine
AI probability engine. Outputs Choice (BUY/HOLD/SELL), Noul (yes/no), Score. Core brain of DIOVRA.
Noul โ JEV Noul Score
Binary probability (0-1). Low noul on risk = risky trade. Higher = safer.
Setup Quality โ JEV Setup Quality Score
0=Poor, 1=Fair, 2=Good, 3=Excellent. Low scores may trigger risk blocks.
Consensus โ Algorithm Consensus
When 3+ indicators agree, DIOVRA shows a consensus signal for cross-checking against JEV.
Confidence โ JEV Confidence Level
Percentage (0-100%) of how sure JEV is about its direction. Higher = stronger signal.
P&L โ Profit and Loss
The difference between your entry price and current/sell price. Positive = profit, negative = loss.
Position โ Position Size
How much of a stock you own. DIOVRA limits single positions to 25% of portfolio.
Kill Switch โ Kill Switch
Emergency circuit breaker. If triggered, all trading is halted. Prevents catastrophic losses.
Slippage โ Slippage
Difference between expected price and actual execution price. Real trading has slippage; paper doesn't.
Drawdown โ Maximum Drawdown
Largest peak-to-trough decline. DIOVRA limits to 10% to protect capital.
IEX โ Investors Exchange
Stock exchange used by DIOVRA for real-time market data. Provides clean, direct data.
โ
Ignoring the confidence thresholdAlways check JEV confidence before trading. Below 70% = weak signal.
โ
Overriding the risk engineIf DIOVRA blocks a trade, listen. The risk engine protects your capital.
โ
Trading every signalJEV says HOLD 55% of the time. Patience is a strategy.
โ
Not journalingIf you don't write why you traded, you can't learn from mistakes.
โ
Panicking after lossesEven 60% win rate means 40% losses. It's about the streak, not individual trades.
Is DIOVRA free?
Yes. DIOVRA is completely free to use โ no credit card, no paid tier. You get a virtual $10,000 portfolio, AI signals, and a trade journal at no cost.
Do I need a password?
No. Enter your email, receive a 6-digit OTP code, and you are signed in. Active sessions are remembered per device and can be revoked from your profile.
Is this real money?
No. DIOVRA is paper trading only: every trade uses virtual cash, so you can practice and learn without any financial risk. It does not connect to a brokerage and is not investment advice.
What is the JEV AI decision engine?
JEV is DIOVRA's probability engine. It outputs a BUY/HOLD/SELL direction with a confidence percentage, a binary Noul score, and a setup-quality score. Its call is cross-checked against 5 technical indicators (SMA 20/50 trend, MACD, RSI, Bollinger Bands, Stochastic) and a risk engine that blocks any trade that fails a safety check. All five indicators vote; a consensus needs 3 of the 5 to agree.
Do my trades and journal persist?
Yes. Your portfolio, positions, trade history, journal entries, settings, and points are saved to your account in PostgreSQL and sync across sessions and devices.
Can I use DIOVRA on my phone?
Yes. DIOVRA is a responsive web app that works in mobile browsers and can be added to your home screen. A native Android app is nearly ready for release, with iOS to follow.
