โš™๏ธ Key Capabilities & Safety Rules

๐Ÿ”„ Sequential 8-Leg Execution

Because Robinhood natively restricts orders to at most 4 legs, 8-leg strategies are safely executed in sequence: Package A (least liquid legs) first, then Package B (remaining liquid legs).

๐Ÿ“ˆ Mid + Edge Pricing (GTC)

Parses live Bid/Ask from the Robinhood DOM to determine exact mid price. Credit: Mid + Edge (demands more credit). Debit: Mid - Edge (demands less debit). Step 1 edge defaults to $0.01; Step 2 defaults to $0.03.

๐Ÿ›ก๏ธ 4-Second Recovery Guard

If any DOM lag, missing leg, or option type mismatch occurs, the bookmarklet waits up to 4s for React to settle. If still unresolved, it clears the order card and restarts that package cleanly.

๐Ÿ›‘ Buying Power Safety Halt

If Robinhood displays "Deposit Funds" instead of "Submit" on the review screen, execution halts immediately and alerts the user to add collateral before proceeding.
