New session

The US equity symbol this session will trade. Each symbol can belong to only one active session.
Dollars to commit to this session. Rejected if it exceeds your free cash, or would push active sessions past 100% of available cash. (Entered in dollars — no percent-of-cash mental math.)
No allocation and no parameters: a Long session just holds a ticker. Create it, then use Buy on the card to purchase shares — each buy claims cash from your free cash at that moment.
Trailing distance in basis points (100 bps = 1%). How far price must move from the reference to arm an order, and the reversal that triggers the fill. Minimum 50 bps.
Fraction of this symbol's budget added to the buy at each additional dip step (compounding, capped at 7 steps).
Fraction of currently-held shares offered at each spike step. Never sells below cost.
How far price must FALL below the reference R (the last action's price) before a buy may arm. 100 bps = 1%.
How far above a lot's cost price must rise before that lot may sell. This is the guaranteed minimum gross margin on every round trip — a lot never sells below cost + this band.
The bounce off the running low that triggers the buy.
The reversal off the running high that sells every cleared lot together (each keeps its own cost+band floor).
Linear sizing: each band-crossing dip buys this fraction of the ORIGINAL allocation. No compounding, no per-session buy cap.
Fraction of CLEARED lots sold per sell event, cheapest-first. Underwater lots are untouchable.
Liquidate everything if price falls this far below weighted-average cost — the ONE sale allowed below the cost floor. 0 disables (not recommended).
Off (default): regular hours only, exactly as before. On: this session also trades Schwab's official pre-market (~7:00–9:25 ET) and after-hours (~16:05–20:00 ET) windows with AM/PM limit orders. Extended now behaves exactly like regular hours: the old spread guard and retreat-cancel are gone, so a wide book no longer blocks a trade — bid/ask and the spread are shown on each symbol so the call is yours. Start with one small session.
On: profit grows this session's deployable budget (compounding). Off: profit is harvested to your account's free cash to allocate elsewhere.

Definitions

What each status means and what it is waiting for.

Neutral-band statuses

Flat waiting
Holds no shares · watching for a dip
Nothing is owned. It waits for the price to fall to the buy arm. While flat, the reference R ratchets upward with the market, so a rally moves the whole buy ladder up rather than stranding it below.
Armed to buy
Dip qualified · waiting for the turn
The dip was deep enough to arm. It is not about to buy at the current price — it now tracks the trough downward and waits for a bounce back up to trough + trail. Arming looks down; firing looks up. The price paid is capped by the buy ceiling regardless of how far the bounce runs.
Holding waiting
Holds shares · watching for a rise
Shares are held and nothing is armed. It waits for the price to rise to the sell arm. That arm sits above the never-sell-below-cost floor by exactly the trail, so a full give-back from the arm still lands on the floor.
Armed to sell
Rally qualified · waiting for the reversal
The rally was high enough to arm. It tracks the peak upward and sells when the price reverses down to peak − trail. Only lots whose own cost floor clears that reversal are sold. If none clear, it disarms and reports sell armed but nothing sellable above cost rather than taking a loss.
Order pending
An order is resting at the broker
Placed and waiting to fill. On a fill, R resets to the fill price and it returns to holding waiting or flat waiting depending on what is left. If it does not fill, the order is cancelled and the peak and trough are wiped — it must arm again from scratch. That is deliberate: a stale episode should not resume against a market that has moved on.

The three price levels

Arm
Where an episode starts. Buy arms when price falls to it; sell arms when price rises to it.
Ceiling / floor
The worst price accepted. Buy ceiling is the most you will pay; sell floor is cost plus the up-band and is never crossed — the strategy will let an order rest unfilled rather than sell below it.
Fires
Where the order is actually sent: the bounce off the trough, or the reversal off the peak, clamped by the ceiling or floor.

Editing parameters

Edits change the derived levels (arm, ceiling, floor) immediately, because those are computed from R and cost. They do not reset R, the phase, the peak or the trough. So editing mid-episode leaves a trough or peak established under the old settings — old trough, new trail. Edit while a symbol is waiting, not while it is armed, and the new parameters apply cleanly from the next arm.

Security

Schwab connection

Start a fresh 7-day Schwab session whenever you want — you don't have to wait for the current one to expire. This opens Schwab's login and brings you back here when you're done.

Sign in with Face ID on this device instead of typing your access key. Your access key and 2FA code always stay available as a backup, so a lost device never locks you out.

Backtest

Replays the strategy on 1-minute history over the last ~3 weeks. Just enter a symbol — band, trail, buy and sell are all swept and ranked for you. Results are approximate; see the notes after running.

Options

Leave blank to use the last ~3 weeks and this symbol's allocated cash (or $10,000 for a new ticker). Catastrophe stop is off for backtesting.

Spread: the round-trip cost is taken from this symbol's own recorded bid/ask — the 90th percentile, doubled, so it leans pessimistic rather than typical. A symbol with no recorded history gets no spread assumption at all, which makes its results optimistic; trade it live for a session first. The figure is a single constant for the whole replay, but real spreads widen exactly when the strategy most wants to trade, so treat it as a floor on cost rather than a forecast. A wide spread mostly shows up as fewer completed round trips, not as losses — the never-sell-below-cost floor still holds.
