Open Source Trading Harness

Set your floor once.
It only moves up.

Automated trailing stops that lock in gains as your position climbs — and execute a clean exit if the floor is breached. You write the rules. The harness enforces them. Your keys, your brokerage, your account.

Drag the floor. Watch it protect the gains.

Same price path, same crash at the end. The only variable is how tight you set your trailing stop. Move the slider and replay to see where the floor would have taken you out — and what the gain would have been if you'd just held.

The floor is the foundation. Here's what's built on it.

Every strategy in FloorPricer is a rule set — you define the parameters, the harness enforces them. Paper-trade each one until you understand the mechanics, then connect real capital.

All examples below are illustrative of paper-trading mechanics only. Not a projection of real returns. See full risk disclosure below.

Trailing Stop

Beginner

Set a floor at X% below the highest price reached. Every time the price climbs to a new high, the floor ratchets up with it — but it never moves down. The moment the price drops through the floor, the harness executes a clean exit automatically.

How the floor moves — step by step

  1. Entry at $100. You set a 10% trailing stop. Floor starts at $90.
  2. Price climbs to $120. Floor automatically ratchets to $108 (10% below the new high). The floor never drops back.
  3. Price pulls back to $107 — below the $108 floor. Harness triggers exit at market. You exit with the gain locked in.
  4. If price kept climbing to $150, the floor would have followed to $135 — still protecting downside.

Trailing stops cannot protect against overnight gaps or extremely fast markets. Illustrative example only.

Ladder Buy

Intermediate

Instead of buying a full position at once, ladder buys automatically scale into a position at pre-defined price levels as the stock falls. Each rung of the ladder buys a fixed dollar amount — so you average down only on the schedule you set, never on emotion.

How a 3-rung ladder works — step by step

  1. You define 3 rungs: buy $500 at $100, $500 at $92, $500 at $85. Total: $1,500 max committed.
  2. Price opens at $100. First rung executes automatically — $500 deployed.
  3. Price drops to $92. Second rung executes — another $500. Your average cost drops.
  4. Price stabilizes above $85 — third rung never triggers. You deploy less than your max.
  5. Each buy automatically gets a trailing stop — the floor follows each rung independently.

Ladder buying does not guarantee a better average cost — price may continue falling past all rungs. Illustrative only.

Wheel Strategy

Advanced

The Wheel is an options income strategy: sell a cash-secured put to collect premium; if assigned, you own the stock — then sell covered calls on the shares you hold to collect more premium. The floor protects you while the wheel turns.

The three phases — step by step

  1. Phase 1 — Sell the put: You sell a 30-day cash-secured put on a stock you'd be willing to own. You collect the premium immediately regardless of outcome.
  2. Phase 2 — Assigned or expired: If the put expires worthless, keep the premium and repeat. If assigned, you own 100 shares at the strike price — which you were willing to pay.
  3. Phase 3 — Sell the call: On your shares, sell a covered call at a higher strike. Collect premium. If called away, you sell above your cost basis. Repeat from Phase 1.
  4. FloorPricer's role: Trailing stop on the underlying position between cycles protects against gap-down scenarios while the wheel turns.

Options trading involves significant risk. The Wheel does not guarantee income — assignment risk and gap risk apply. Paper-trade extensively before using real capital.
