Markets become a stimulus.
Price direction, consistency and volatility turn into approach and avoidance inputs. Eight assets, one shared observation window.

EXPERIMENT 001 / DROSY
A fruit fly walks into the market.
We keep the receipts.
Live prices become neural signals. Follow the fly, watch its brain respond, and see every move in one open portfolio.

THE METHOD, MINUS THE MYSTERY
Built to forage.
Now following
the market.
Not a crystal ball. A small neural circuit facing a very big question.
Model & data sources ↗The circuit does its thing.
1,045 modeled neurons react through 17,224 recorded connections. Motor activity becomes a buy, sell or hold signal.
Every move leaves a trail.
Confirmed signals meet the portfolio limits. Each allocation, price and cost is saved. The equal-weight basket keeps the comparison honest.
A few things worth knowing.
Is this a real fly trading real money?+
Drosy runs a software model of a fruit-fly locomotor circuit. Its shared portfolio starts with $1,000,000 in paper capital and follows public market quotes. It does not hold deposits or place real trades. The displayed activity comes from modeled neurons, not a live insect.
What decides a buy, sell or hold?+
Fresh price history drives approach and avoidance neurons. The readout is the left hind-leg motor rate minus three times the left front-leg motor rate. Scores of +5 or higher can buy; −3 or lower can sell. Two consecutive responses, source freshness and portfolio limits must also agree. This mapping is designed for the experiment and is not evidence of predictive skill.
What happens when market data stops?+
Quotes older than two minutes cannot trigger trades. The portfolio retains the latest available marks and shows the delay. A gap resets the affected asset's observation window. Missing time is never filled with invented trades.
What costs and limits are included?+
Each fill includes an estimated 0.10% fee and 0.05% slippage. New entries are limited to 2% of equity, 15% per asset and 55% total exposure. An 8% drawdown pauses new entries. Assets have a twelve-minute cooldown and buys are at least ninety seconds apart. A 2.5% decline from an observed position peak raises avoidance; it does not guarantee a stop price.
How does Robinhood Chain fit in?+
Drosy is a fruit-fly meme project for the Robinhood Chain community. The public experiment is an off-chain research portfolio. Reference assets and portfolio figures are separate from the DROSY community token; following the experiment does not require a wallet or a deposit.
Can I check the decisions myself?+
Yes. Select a market to inspect its inputs, response and latest quote time. Every executed paper allocation is stored in the shared ledger, and the complete trade history is available as a CSV download.
