Trade the book, not the chart.
Friend Strategy Trader watches every exchange at the best bid and ask, adds up the size on each side and acts the moment one side overwhelms the other — then exits as soon as the book turns.
Built for the tape reader who never blinks
The same rule an experienced trader applies by eye on a Level II window, executed every 100 milliseconds, on several tickers at once, without fatigue.
Whole-market touch
Sums displayed size across NASDAQ, ARCA, BATS, IEX, NYSE and every other venue at the best bid and ask — not just one exchange.
Your ratio, your rules
Entry and exit multipliers, venue majority, tape confirmation, no-chase and confirmation delays — set per ticker, changed live.
Exits on the book
The position closes at market when the imbalance fades or turns against you. A profit guard locks in a tick when price pulls back.
Trading basket
Run several symbols side by side, each with its own share size and parameters, with a live pressure gauge per row.
Fast execution
Orders go through the Webull OpenAPI on a dedicated thread, so the strategy keeps watching the book while the broker works.
Research built in
Every session records book snapshots, signals and fills. Replay days tick by tick and compare parameters before risking money.
How it works
One simple, transparent rule — no black box.
Read
IBKR Level II data streams the full depth of book for each ticker in your basket.
Measure
At the best bid and ask, size from every venue is summed. The gauge shows who leads and by how much.
Enter
When one side reaches your Entry multiplier (for example 5:1), a marketable limit order is sent at the touch.
Exit
When the pressure decays to your Exit multiplier, the position closes at market. One position per ticker, no pyramiding.
Screens
Screenshots of the trading basket, the pressure gauges and the parameter editor are shown to approved users.
