20-Day Momentum + Trailing Stop on Webull

Buy after a +10% four-week burst and let a 10% trailing stop manage the exit. Deployed to your own Webull account — no code, your assets never leave the broker.

The short version: connect Webull once, deploy the momentum breakout template with its own cash allocation, and DeployQuant runs the rules every session — entries, resting exits, and the journal that explains each decision. Median backtested CAGR across 59 ETFs: 0.0% (2021-01-04 → 2026-07-17).

Setup on Webull

  1. Connect your Webull account from the Brokerage page — the connection carries trade and read permissions only, never withdrawals.
  2. Build a strategy in the Lab (blocks or AI), or fork one from the community, and backtest it on years of minute data.
  3. Deploy it to Webull with a cash allocation — the strategy runs in its own isolated sleeve, so other holdings and other strategies are untouched.
  4. Type the live-trading confirmation. Until you do, nothing real is sent.
  5. Profit targets rest at Webull as real GTC limit orders; pause the strategy or the whole connection anytime.

The strategy

  1. WHEN the market opens · IF not invested AND the 20-day return > +10% · THEN buy with 98% of the sleeve
  2. WHILE invested · a managed trailing stop follows 10% below the position's high-water mark

Good for: high-momentum assets where trends extend — semiconductor and leveraged tech ETFs show the archetype.
Watch out: buying strength means buying high; when a burst immediately reverses, the trail exits about 10% below the entry.

Frequently asked questions

How do I automate momentum breakout on Webull?

Connect Webull to DeployQuant (trade & read permissions only), pick the 20-Day Momentum + Trailing Stop template or describe it in English, backtest it on your chosen ETF, allocate cash, and confirm live trading. The strategy then runs every session in its own sleeve inside your Webull account.

How does the trailing stop work when deployed live?

DeployQuant maintains it as a managed order: it ratchets up as the position makes new highs and triggers a market exit when price falls through it. It never widens.

Backtests are hypothetical, computed by DeployQuant's engine on minute-resolution consolidated US market data (2021-01-04 to 2026-07-17, $10,000 starting capital, no margin, fees and slippage not modeled) and do not guarantee future results. Nothing on this page is investment advice. Live trading involves risk of loss.
