A trading workbench that proposes, checks and records orders, and leaves the decision to send them with you.

The sidebar is laid out in the order a trading day runs.

The strip at the top says where you are, whether the data is fresh, and whether anything is waiting for you.

From an idea to a filled paper order, and where to see the result afterwards.

By default, nothing. Here are the exceptions, and where each one is written down.

Every ticket that needs your click is listed on the Overview, oldest first.

Symbol, side, size and limit price, checked against your limits before it can be proposed.

A draft is an order you have thought about but not proposed. It costs nothing to keep.

A rule that proposes an order at a time, on an event, or when a price crosses a level.

Decide where you get out before you get in, and write it down where the system can act on it.

One button, on every page, that stops every order until a person clears it.

The local record and the broker disagree. Find out why before doing anything else.

Passive, aggressive or your own: how big positions can be and how much can be invested at once.

What each closed trade made, and which part of the decision it came from.

What is running, what it has done on paper, and what it must prove before it earns more.

What to do next session, most urgent first, each with the measurement behind it.

Fees and spreads, and what they add up to at your turnover over a year.

⌘K (Ctrl+K) to jump anywhere, B to collapse the sidebar, R to refresh.

Decide where you are wrong while you still have no position to defend.

Confirm soon after you propose, or write a new ticket.

A fixed fee per order is a bigger slice of a small trade.

Wait for enough round trips before concluding that something works or does not.

Rules propose overnight and at the open. Look before they go stale.

A note on why you made a trade is what lets you learn from it later.

Dark is the default, for reading before the open. The toggle is at the right of the status bar.

A small piece of ownership in a company, priced continuously by buyers and sellers.

US stock exchanges trade 9:30 a.m. to 4:00 p.m. Eastern, Monday to Friday, except holidays.

You buy at the ask, sell at the bid, and the gap between them is a cost you pay every round trip.

A market order fills now at whatever price is available; a limit order fills only at your price or better.

How long an unfilled order stays open.

A sale’s cash is settled the next business day. In a cash account, that timing matters.

A cash account cannot borrow. A margin account can, and has its own rules.

Several unrelated holdings are less likely to all fall at once than one big one.

How much a price swings, and how far an account has fallen from its peak.

An index tracks a basket of stocks. The S&P 500 is about 500 of the largest US companies.

Cash paid to shareholders, and a change in share count that leaves the value the same.

Companies report results each quarter, and prices can jump between one close and the next open.

Two opposite ideas: what rose keeps rising, or what moved too far comes back.

A backtest replays a rule on past prices. Try enough rules and one will look great by luck.

Return per unit of risk, adjusted here for how many ideas were tried to find it.

In the US, gains on positions held a year or less are usually taxed as ordinary income.

One hundredth of a percent: 100 bps = 1%.

An order fills when it trades. A partial fill trades only some of the shares.

Shares times price: the dollar size of a position or order.

The difference between the price you expected and the price you got.

Checking the local record against the broker’s, share by share.

How far a strategy is trusted to act without a person.

Trading with real prices and pretend money.
