How it uses Jev
The paper-trading demo sends a BTC five-minute market snapshot to Jev. One Choice estimates whether the market will settle UP or DOWN relative to its opening reference; a separate Choice asks whether a paper trader should buy UP, buy DOWN, or wait now. The entry answer informs a simulated signal, subject to data, risk, quote-depth, and fee checks.

INSTRUCTION
Should a paper trader with no open position buy UP shares, buy DOWN shares, or wait now, accounting for outcome value, current asks, fees, depth, time, and uncertainty?
STATE
The source-defined model state contains the active market and reference price, seconds remaining, recent reference-price history and returns, UP/DOWN order books, fee schedule, and optional Binance perpetual features explicitly marked as auxiliary. Values change each cycle; this is not an observed market snapshot or Jev output.

App workflow
- Collect and validate a market snapshot
The engine obtains reference prices, order books, market timing, fee data, and optional auxiliary perpetual-market features; stale or invalid observations block evaluation.
- Evaluate outcome and entry separately
Jev returns probabilities for the terminal direction and for the entry actions. The entry policy uses the latter when configured as the entry decider.
- Recheck and simulate execution
After inference, the engine fetches fresh data and rejects stale or changed-round results. It applies risk and depth checks, records paper trades in the ledger, and later settles positions from market resolution.
Why it is interesting
It asks Jev to separate terminal-outcome probabilities from the distinct decision to trade at current prices. The app then refreshes quotes after inference and uses a paper ledger, so a model preference alone cannot bypass execution and account constraints.
