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.

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.
Tuned for every ticker
Each ticker's entry and exit settings are tuned and kept up to date for you. You decide the share size and the hours it trades.
Exits on the book
The position closes at market as soon as the book stops backing it, and a market stop protects every trade.
Trading basket
Run several tickers side by side, each in its own slot with its own share size and a live pressure gauge.
Fast execution
Orders go through the Webull OpenAPI on a dedicated thread, so the strategy keeps watching the book while the broker works.
SIM and LIVE
Trade on paper (SIM) or with real money (LIVE) from the same screen, with their results kept apart.
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 clearly outweighs the other, a limit order goes out at the best price.
Exit
When the book turns against the position, it closes at market. One position per ticker, no pyramiding.
