Delta Monitoring & Alerts

Automated email alerts when a trade's delta or P&L crosses the limits you set

How Monitoring Works

Delta Monitoring watches your open trades for you. Stratsigma periodically recalculates each monitored trade's aggregate delta and total P&L in the background and emails you when either crosses the limits you have set, so you do not have to check the position through the day.

Aggregate delta is built from the same pricing model used across the app: each leg's delta is multiplied by its quantity and the contract multiplier (100) and summed across all legs, with any underlying shares in the trade added directly.

Setting Up Alerts

Alerts are set per trade, in the Alerts section when you create a trade, or later from Trade Detail. There are two types, on separate tabs:

• Delta: set an Upper and Lower limit, plus a Tolerance, a buffer so small oscillations around a limit do not trigger an alert (a breach counts only once delta moves past the limit by more than the tolerance)
• P&L: set a Loss Limit (a negative dollar amount, e.g., -500) and a Profit Target (e.g., 1000), measured against the trade's total P&L

For each type, choose whether to be alerted on breach of limits, on return within limits, or both. You can also set a Start and End time (ET) so alerts only fire during a daily window, such as market hours.

Email Delivery

Alerts are emailed to your account address. You receive one email per event: a breach email when a trade first crosses a limit, and a return email when it moves back within limits. Stratsigma tracks each trade's alert state, so you are not flooded with repeated emails on every monitoring cycle.

If delta cannot be calculated because market data is temporarily unavailable, Stratsigma sends a notice and follows up automatically once data is restored.
