Mathematical precision for traders

Trade journaling,
rebuilt as a system

Every P/L number traceable to fills. FIFO lot matching. No black boxes. Built for traders who demand correctness over convenience.

Rule-based system
Deterministic math

The problem with trade journals

Most trade journals are glorified spreadsheets with vague P/L numbers, hidden calculations, and no audit trail. When your numbers don't match your broker, you have no way to know why. We built AccelerateJournal to fix this.

Core Principle

Fills are truth. Everything else is derived.

FIFO Lot Matching

Every lot tracked individually. First in, first out. Exact cost basis for every position.

Full Audit Trail

Raw import rows preserved. Every rejected row has a reason. Replay any import.

Any Broker CSV

Flexible column mapping. Import from TOS, IBKR, Webull, or any broker. Save templates.

Long & Short

Correct P/L for both directions. Short covering, position flips, partial fills—all handled.

Options Support

100x multiplier applied correctly. OCC symbol parsing. Single-leg and spreads.

Transparent Grouping

See exactly why fills are grouped. Deterministic algorithm based on position lifecycle.

The math that drives edge

Your realized P/L is computed using FIFO lot matching. When you close a position, the oldest lots are matched first. Fees are deducted. The formula is simple and deterministic.

P/L Formula (Long)
P/L = (exit_price - lot_cost) × quantity × multiplier
Lot cost is the price you paid when opening that specific lot
Multiplier is 1 for equities, 100 for options
Fees & commission are subtracted from the final P/L
Example: Partial Exit
Lot 150 shares @ $48.00
Lot 250 shares @ $52.00
Sell75 shares @ $55.00
FIFO Matching:
50 from Lot 1:+$350.00
25 from Lot 2:+$75.00
Total P/L:+$425.00
