normalizeSymbol(
symbol):string
"ETHUSDT", "ETHUSDT.P", "ETH/USDT", "ETH-USDT" → "USDT_ETH" (the
host puts the chart's exchange in front); "BINANCE:ETHUSDT" →
"BINA_USDT_ETH", "BINANCE:ETHUSDT.P" → "BIFU_USDT_ETH", "COINBASE:BTCUSD"
→ "GDAX_USD_BTC". "USDT_ETH" and "BINA_USDT_ETH" pass through. An
unknown prefix is kept as is, and the host rejects its exchange.
