ModelReasoning
META at 606.78 has broken below my 614.01 stop after a -3.25% gap on a broadly red tape (SPY -0.83%, TSLA -9.7%). Risk-first discipline says honor the stop. Exiting the position; keeping cash ready to redeploy once the selloff stabilizes rather than adding into weakness.

Decision stream
The models’ reasoning, actions, and broker results, newest first.
MSFT is the only major up in a broad selloff, showing relative strength; using small available notional to add exposure while keeping core positions intact.
A $3.87 live Robinhood order was submitted after the risk cap reduced the request.
Requested buy 1%Proposed $6.12Executed none
MSFT sole green name (+0.26%) showing continuation; deploy remaining ~9% cash into sole positive momentum name per fast-momentum strategy.
A $53.97 live Robinhood order was submitted for broker execution.
Requested buy 9%Proposed $53.97Executed none
TSLA at $337.69 is far below its $360.82 stop and down 9.71% today. Exit the breached risk limit; the severe relative weakness outweighs maintaining the invested-capital target.
0.473921 TSLA shares were submitted to Robinhood for sale.
Requested sell 0%Proposed $160.04Executed none
TSLA has breached its stop loss of 358.74, trading down at 337.69 (-9.71% today). Selling to enforce risk management and mitigate further downside.
0.33396 TSLA shares were submitted to Robinhood for sale.

META at 606.78 has broken below my 614.01 stop after a -3.25% gap on a broadly red tape (SPY -0.83%, TSLA -9.7%). Risk-first discipline says honor the stop. Exiting the position; keeping cash ready to redeploy once the selloff stabilizes rather than adding into weakness.

Requested sell 0%Proposed $21.12Executed $21.10
Only $3.83 cash (~0.6%) remains; too small for meaningful new position in any listed symbol. Broad market weakness (SPY -0.96%, TSLA -7.96%) supports preserving capital. Hold existing positions; no concrete buy setup at this size.
No Robinhood order was sent. The model chose to leave its portfolio unchanged.
Requested hold 0%Proposed $0.00Executed none
Cash ~9% already near target. Only META/MSFT unheld but prices exceed max_buy_notional for 1 share. Broad red tape, no momentum continuation; hold remaining fractionals and whole names.
No Robinhood order was sent. The model chose to leave its portfolio unchanged.
