Defense First: Setting Take-Profit and Stop-Loss with the Risk Control Hub
What the Sell Put Equity Curve Looks Like
Small win, small win, small win, small win... then one big loss hands back half of all those small wins.
That's not exaggeration—it's the natural shape of a short-premium strategy: capped gains (the premium), amplified losses (getting assigned into a crash). Whether a Sell Put account survives long-term doesn't depend on how well you win; it depends on whether you can cage your losses.
The cage is rules. My rules used to live in my head and on a sticky note; now they live in the Risk Control Hub—machines enforce discipline more reliably than I do.
Seven Rules and What Each One Guards
| Rule | What It Guards | When Triggered |
|---|---|---|
| Minimum OTM % | Entry floor—no trades below this cushion | Hard-blocked by the Order Desk's pre-trade checks |
| OTM Alert % | How eroded a position's cushion can get before it's alarming | Alert |
| Take-Profit % | What share of the premium in floating profit triggers harvest | Alert |
| Stop-Loss % | How much floating loss means admitting defeat | Alert |
| Days to Expiry | Positions must be handled this many days before expiration | Alert |
| Concentration Cap % | Max share of net assets in one underlying's assignment obligation | Pre-trade block + alert |
| Quote Freshness | How many minutes before data counts as stale | Stale data clearly flagged |
Once confirmed, rules become official—and the Order Desk's pre-trade checks treat them as hard gates.
Setting Thresholds: Run the Defaults First, Then Tune
Beginners always ask: take-profit at 50% or 70%? Stop-loss at 100% or 200%?
My advice: first, use the system's default alert lines—don't customize on day one. Second, run normally for a month and let some alerts fire naturally. Third, review every alert at month-end—loosen the ones that cried wolf, tighten the ones that missed real risk.
A few of my own anchors, for reference only:
- Take-profit at 50%: Sell Put profits come fast early and slow later; after capturing half, the remaining time value is thin—better to free up the margin
- Stop-loss by distance to strike: I generally consider stopping out when the price is within 5% of the strike—if it falls in-the-money, the loss becomes real
- 5 days to expiry: gamma peaks in expiration week, and small price moves get amplified into violent P&L swings
- 25% single-underlying concentration: no matter how bullish I am, I won't let one name's big loss hurt the whole account
These numbers aren't standard answers—they're my account's answers. Yours have to come from your own data.
What to Do After an Alert
Alerts push to the dashboard, and email notifications can be configured. The action checklist after an alert:
- OTM alert: check whether the underlying's fundamentals changed—if not, hold; if so, consider rolling
- Take-profit alert: buy to close right away—don't get greedy for the last bit of time value
- Stop-loss alert: close first, review after. Never reverse that order
- Expiry alert: decide between assignment, rolling, or closing—all three are fine; what's not fine is leaving it unattended
