This is a paper-trading prototype for Solana memecoins. It scans the newest token profiles from the free DexScreener public API, scores each token with a HEURISTIC rug check (7 equally-weighted checks — it is not a full rug audit: DexScreener exposes no mint/freeze-authority or holder-distribution data), and — when auto-trade is on — buys the best-scoring token that passes every entry gate. Exits (take-profit, stop-loss, trailing stop, time stop) are checked on every scan poll. Nothing here moves real money. Simulated slippage and fees are applied to every fill.

• Starting capital $10,000 (editable). Risk per trade 1% of equity; position size = equity × risk% ÷ stop-loss% (e.g. $10,000 × 1% ÷ 15% = $666.67, 6.7% of account). Max trade $1,000. Max total deployment cap 60% of account across all open positions (1–100%) — a portfolio cap, not a trade size. Slippage 1%. Fee 1%.
• Auto-trade: one buy per scan, max one per 5 min, max 5 open positions, max 10 auto-trades/day, max 2 trades per token per day, 30-min re-entry cooldown after a stop-loss on that token, daily halt at −5% day P/L or 3 consecutive losses.
• Entry gates: rug score ≥ 80/100 and verdict PASS; liquidity ≥ $25,000; 24h volume ≥ $10,000; pair age 10 min – 6 h; FDV $100k–$5M; 5m buys ≥ sells AND 1h buys ≥ sells; momentum not fading vs previous scan (5m volume and buy pressure not both down); 1h price change between −20% and +300%.
• Rug check (HEURISTIC, 7 equally-weighted checks, PASS ≥ 80, WARN 45–79, FAIL < 45): liquidity depth, 24h volume, volume/liquidity ratio, buy pressure (1h buys share), dump check (5m sells share), pair age, FDV vs liquidity.
• Sizer: size = equity × risk% ÷ stop-loss%. The sizer shows the actual $ risked if the stop is hit and the position as % of account; if a cap (max trade, cash, total-deployment room) shrinks the size, the actual risk is below the intended risk%.
• Exits: TP1 +30% sells 50% and banks it, remaining stop moves to breakeven; TP2 +80% sells the rest; trailing stop −12% from peak once up +20%; stop-loss −15% (breakeven stop after TP1); 30-minute time stop.
• Optimizer bot (ON by default): watches closed trades since the last rule change; when a slice is clearly losing (5+ trades, negative expectancy, win rate ≤ 40%) it changes exactly one rule, logs it, then freezes for 20 more closed trades. It never changes starting capital or the max total deployment cap, and never resets the account.

• Solana Memecoins — live (default). DexScreener data, 24/7. Rules above are the memecoin rules.
• Crypto Majors — BTC/ETH — live. Binance public API (no key), 24/7. Entry: price above the 20-period SMA (1h), 1h change ≥ 0%, taker-buy share ≥ 50% on the last closed 1h candle, 24h quote volume ≥ $500M. Exits rescaled: TP1 +8% (sell 50%), TP2 +15%, trailing −7% from peak once +10%, stop-loss −3%, 24 h time stop (exits only if still under +2%). Max 2 open positions; max position 25% of equity. Slippage/fee 0.1% each (Binance spot taker).
• US Stocks — SPY/QQQ — unlocks when your Alpaca paper API keys are saved in Settings (below). Alpaca Market Data, free IEX feed, regular session only, 09:30–16:00 ET, Mon–Fri — never the overnight session, even though the broker allows 24-hour trading, because there is no liquidity overnight. Entry: price above the 20-period SMA (1h), 1h change ≥ 0%, last closed 1h volume ≥ its 20-bar average, ADV ≥ $10M (IEX proxy), spread ≤ 0.1%. Exits rescaled: TP1 +5% (sell 50%), TP2 +10%, trailing −4% from peak once +5%, stop-loss −2%, 5-day time stop. Max position 50% of equity. Fee 0% (Alpaca paper charges no commission), slippage 0.05%. Earnings blackout and US market holidays are not yet handled — a stale-data scan skips entries.
• Forex Majors — locked: coming later.
• Perpetuals — locked: coming later, only after spot majors works (100+ paper trades), low leverage only.

Each market keeps its own paper ledger — separate starting balance, positions, trades, logs and settings. Switching markets never touches another market's ledger. Position sizing is the same formula everywhere: equity × risk% ÷ stop-loss%.
