Greeks Triggers

Greeks Triggers allow adjustments to fire based on real-time Options Greeks — the mathematical risk parameters that measure how an options position responds to price, time, and volatility changes. This is the most sophisticated adjustment trigger available, enabling institutional-grade autonomous hedging.

Available Greeks

Greek	Measures	Why It Matters for Adjustments
Delta (Δ)	Sensitivity to underlying price change	If Delta skews too far, your “neutral” position is no longer neutral
Gamma (Γ)	Rate of Delta change	High Gamma means Delta can shift rapidly — your position is unstable
Theta (Θ)	Time decay rate	Monitor how much value you’re gaining/losing per day from time decay
Vega (ν)	Sensitivity to volatility change	If Vega is too high, a VIX spike could devastate your position

Evaluation Modes

Net Mode (Portfolio-Wide)

Evaluates the combined, summed Greek exposure across all active legs in the portfolio.


Portfolio:
  Leg 1:  Buy Call   →  Delta = +0.60
  Leg 2:  Sell Call  →  Delta = -0.35
  Leg 3:  Sell Put   →  Delta = +0.20
                        ─────────────
  Net Portfolio Delta =  +0.45

Trigger: If Net Delta > 0.40 → FIRE ADJUSTMENT

Use When: Managing the overall risk of complex multi-leg positions (Iron Condors, Straddles, etc.).

Single Mode (Individual Leg)

Evaluates the Greek of a specific individual leg in isolation, identified by its leg number (sr_no).


Trigger: If Leg 2 Vega > 0.5 → FIRE ADJUSTMENT

Use When: A specific sold option is becoming disproportionately risky, even if the net position looks fine.

Configuration

Parameter	Description
Greek	Select Delta, Gamma, Theta, or Vega
Mode	Net (portfolio) or Single (specific leg)
Operator	`>`, `>=`, `<`, `<=`
Value	The threshold that triggers the adjustment
Consecutive Bars	How many bars the condition must sustain

Example Configurations

Rule	What It Does
`Net Delta > 0.40`	Portfolio is getting too directionally biased → rebalance
`Net Delta < -0.40`	Portfolio is too bearishly exposed → rebalance
`Net Gamma > 0.10`	Position is unstable — Delta can shift rapidly → reduce risk
`Net Vega < -15`	Too much short volatility exposure → hedge before VIX spike
`Leg 2 Vega > 0.5`	Specific sold option’s vol exposure is dangerous → roll it

The Trading Edge

Why Greeks Beat PnL-Based Adjustments

Option prices often lag during extreme, sudden volatility expansions. PnL reflects what has already happened. Greeks reflect what will happen if conditions continue.

By triggering adjustments when your portfolio’s Net Delta or Gamma exposure mathematically blows out, your system auto-hedges the position before your PnL even reflects the impending loss.

This is the same principle institutional prop desks use — they monitor Greeks in real-time and hedge automatically. PnL-based stops react after the damage. Greek-based adjustments prevent the damage from occurring.

Real-World Example: Delta-Neutral Iron Condor Management


Strategy: Short Iron Condor on Nifty
  Leg 1: Sell 22000 CE  (Delta = -0.30)
  Leg 2: Buy 22200 CE   (Delta = +0.15)
  Leg 3: Sell 21800 PE   (Delta = +0.30)
  Leg 4: Buy 21600 PE    (Delta = -0.15)
  
  Net Portfolio Delta ≈ 0.00  (Delta neutral at entry)

Adjustment Rule:
  IF Net Delta > 0.30 for 2 consecutive bars
  THEN Close Leg 1 (tested Call) & Re-Enter at ATM+3
  
What happens:
  Market rallies → 22000 CE comes under pressure → Net Delta drifts to +0.35
  → Adjustment fires → Leg 1 closed → New Sell CE placed further out at 22150
  → Portfolio re-neutralized automatically

Combining with Indicator Triggers

You can have multiple adjustment rules running simultaneously:


Adjustment Rule 1: Greeks-based
  IF Net Delta > 0.40 for 2 bars → Close & Re-Enter (roll strikes)

Adjustment Rule 2: Indicator-based  
  IF RSI(14) > 80 for 3 bars → Close Buy-side positions (take profit)
