How stock trading works on Atheneo.

Four kinds of order

• Market — fill now at the best price available. Fast, and the price is whatever the market gives you.
• Limit — fill at your price or better, or not at all. The ladder places these with one click on a rung.
• Stop — becomes a market order once the price touches your level. The way a loss is capped. Stop-limit is on the backlog.
• Bracket — an entry with a stop and a target attached. On paper the stop rests at the brokerage, so it survives anything on our side. A connected Webull account takes one order at a time; place the stop from the Orders tab once the entry fills.

Sessions

Regular hours are 9:30 to 4:00 Eastern. You can let your own orders run into pre-market (4:00–9:30), after hours (4:00–8:00 PM), and overnight — a setting under Trade. Thinner markets, wider spreads; a limit order is the sane instrument out there. Overnight →

What a fill is

A fill is the broker telling us shares changed hands, at a price, at a time. Partial fills are normal on larger orders. Every fill is drawn on the chart, listed on Orders, and kept in the Ledger forever.

Realized and open P&L

Open is what your positions are worth right now against what you paid. Realized is what you have actually closed, and it lands on the day you closed it. A short opened Tuesday and covered Wednesday is Wednesday's money. The account card shows both, and the day's total is the broker's own figure.

Buying power

Your broker decides what you can buy. Atheneo shows the broker's figure and, where the broker reports one number but not another, says so rather than guessing. Margin and cash →

The ledger keeps it all

Every order the broker has ever seen on an account — filled, working, cancelled, expired — with the time it was placed, the price, and the P&L on the order that closed the trade. Nothing on a brokerage-connected account can be typed over.
