Order blotter

Each order shows Claude's confidence against the 0.6 minimum (the dark tick), and the risk layer's ruling.

BTC-USD BUY $1,000.00 fill @ 83,018.09 Filled

Long-term uptrend intact: price is above the 50-day (80.7k) and 200-day (71.9k) averages after a 3% weekly pullback. Starter position at 10% of the account, leaving room under the 25% crypto cap.

Confidence 0.65

Risk layer: approved at full size

ETH-USD BUY $600.00 at 2,508.75 Blocked

Down 7.5% this week and below its 20- and 50-day averages. Momentum is weak, so this was a low-conviction probe.

Confidence 0.45

Risk layer: confidence 0.45 is below the minimum of 0.6

SPY BUY $1,500.00 at 778.57 Blocked

Core index position: SPY is near its 52-week high and above its 50- and 200-day averages.

Confidence 0.70

Risk layer: US market is closed, so stocks and ETFs can't be traded now

The ETH and SPY orders were sent on purpose to show the risk limits at work. A normal run wouldn't submit orders it expects to be rejected.

Notes for the next session

Claude's only memory between runs. The next session starts by reading this.

BTC
Starter 10% at ~83k. Add up to 15% if it reclaims the 20-day average (~84.4k). Exit if it closes below the 50-day average (~80.7k).
ETH
Weak: below its 20- and 50-day averages, −7.5% on the week. Buy on a reclaim of 2,660; ignore below 2,400.
SOL
−8.6% on the week but above its 50-day average (108.5). Watch 105–108 for an entry.
SPY
Open a core position (~15%) at Monday's open if it's still above its 50-day average (767).
Macro
News flow is thin. The main drivers are interest rates, inflation data and ETF flows.
