v3.6.0b

[v3.6.0b] - 2026-09-14

A durable record of every order, a webhook that no longer makes TradingView wait for the
trade, and the stock-side counterpart of v3.5.1b's balance-fee fix.

Added

• Order journal — every order attempt (filled, rejected, errored, insufficient
  balance, market closed) is now appended as one JSON line to src/logs/orders.jsonl,
  fsync'd and never rotated. Previously the only record was tradleware.log, which
  rotates away and left nothing to reconstruct a trade after the fact. Crypto and stock
  rows read the actual per-unit fill price correctly and asymmetrically — crypto's
  average/cost (ccxt's price is only the requested price, often 0/None for a market
  order), stock's price directly (IBKR resolves it before returning).
• CSV-formatted access log for unauthenticated dashboard visits — scanner and bot
  traffic is routed to its own file (access.log), on a logger with no Gotify wiring at
  all, so it can no longer page regardless of GOTIFY_LOG_LEVEL. Previously a lowered
  log level for an unrelated reason could turn routine internet background noise into a
  notification flood.

Changed

• The webhook now acknowledges a signal immediately and executes the order in the
  background, instead of holding the connection open for the full balance-fetch +
  exchange round trip (~10s). TradingView's own webhook timeout is a few seconds, so it
  was marking successful trades as failed, not only genuine errors. The synchronous
  response no longer carries the order id, fill price, or quantity — none of that exists
  yet at acknowledgement time — every outcome is visible via the log, Gotify, and the
  order journal instead. The per-bot execution lock still serialises execution; it just
  does so in the background rather than holding the HTTP connection open.
• Crypto orders no longer fetch the account balance twice per order. The webhook
  handler already fetches it once to validate the signal, while the per-bot lock is held
  — reused instead of being fetched again inside create_order, cutting 3-4s off every
  order.

Fixed

• A stock buy sized at 100% of the account's cash could fail on IB's own commission —
  the same shape as the crypto taker-fee bug fixed in v3.5.1b. Whole-share sizing leaves
  at most one share's worth of cash unspent (zero when price divides cash evenly);
  fractional-share sizing leaves even less. IB's commission (~$0.005/share, $1.00 minimum)
  is now reserved before sizing, only when the order would not otherwise fit.
