+Trading rules now implemented:
+- Bot syncs CoinEx public market rules: min amount, min quote amount, amount precision, price precision, maker/taker fee placeholders.
+- Market rules are stored in table market_rules.
+- Endpoint POST /api/v1/market/rules/sync manually syncs rules.
+- Endpoint GET /api/v1/market/rules lists stored rules.
+- Monitor automatically attempts CoinEx rules sync on first run.
+- One market = one open trade: duplicate open position on same market is blocked.
+- Bot rotates markets and skips markets with open positions, so it does not get stuck on one market.
+- For sell/close in demo, bot closes the full available market position amount from DB.
+- For future live mode, close flow must verify available asset balance by CoinEx API before sending order.
+
 Mode names:
 - demo: virtual demo account, simulated balance, simulated orders, PnL, trade history, reset balance
 - live: selected with the permanent Demo / Live toggle or trade_mode=live
