fomc algo response - rate hold, volatility spike, profits

fomc day.

rates held. powell dovish. markets ripped.

algos crushed it.

the setup
#

going into FOMC I was 90% cash.

had 3 conditional orders ready:

  1. long ES if break above 4520
  2. short ES if break below 4480
  3. long VIX calls if spot VIX > 21

what happened
#

2:00pm: fed holds rates. no surprise.

2:30pm: powell presser starts. tone dovish. mentions “progress on inflation.”

2:45pm: ES breaks 4520. long triggered.

3:15pm: ES hits 4545. +25 points. closed half.

4:00pm: ES at 4558. closed rest.

total ES trade: +$2,180 on 2 MES contracts

volatility play
#

VIX spiked to 19.2 during presser.

then crushed to 15.8 by close.

had VIX puts positioned for this exact scenario.

VIX puts: +$680

options premium
#

sold SPX 0DTE put spreads at 2:45pm when direction confirmed.

0DTE premium: +$420

theta decay is beautiful when you know the direction.

total fomc day
#

ES futures: +$2,180

VIX puts: +$680

0DTE premium: +$420

total: +$3,280

best single day since june.

the algo response logic
#

class FOMCResponseAlgo:
    def __init__(self):
        self.fomc_time = datetime.strptime("14:00", "%H:%M")
        self.presser_time = datetime.strptime("14:30", "%H:%M")
        self.breakout_levels = {}

    def pre_fomc_setup(self, es_price: float) -> dict:
        """Set breakout levels 30 min before announcement"""
        range_pct = 0.008  # 0.8% breakout threshold

        self.breakout_levels = {
            'long_trigger': es_price * (1 + range_pct),
            'short_trigger': es_price * (1 - range_pct),
            'stop_long': es_price * (1 + range_pct / 2),
            'stop_short': es_price * (1 - range_pct / 2)
        }
        return self.breakout_levels

    def check_breakout(self, current_price: float) -> str:
        """Check for directional breakout"""
        if current_price > self.breakout_levels['long_trigger']:
            return 'LONG'
        elif current_price < self.breakout_levels['short_trigger']:
            return 'SHORT'
        return 'FLAT'

simple but effective. don’t predict the fed. react to the market’s reaction.

triple witching friday
#

2 days away.

$5.1 trillion in options expiring.

usually choppy. will reduce position sizing.


11:38pm wednesday. fomc day crushed it. +$3,280 total. rates held, powell dovish, ES broke out +38 points. played the breakout with ES futures (+$2,180), VIX puts (+$680), and 0DTE premium (+$420). best day since june. triple witching friday coming.
