On the SignalsDeck dashboard, every coin has a Coinbase column and a Premium column sitting next to the Binance price. Most sites only show one exchange. We show two — and the gap between them carries a specific signal that professional traders watch closely.

Two prices for the same asset

Bitcoin trades simultaneously on hundreds of venues. The price you see depends on which exchange you look at, and the dominant trading pair on each:

In a liquid, efficient market these should be nearly identical after adjusting for fees and spread. When they diverge persistently, it tells you something about who is buying.

Why Coinbase specifically?

Coinbase is the dominant US retail and institutional spot exchange. When US-based buyers — including ETF inflows, institutional desks, and retail investors — are aggressively acquiring Bitcoin, they tend to push Coinbase’s price above Binance’s.

The logic: US institutions cannot easily arb between Coinbase and Binance (regulatory barriers, KYC differences, banking rails). Korean retail arbitrage with Kimchi Premium was similar. The premium persists because the capital cannot flow freely to close the gap instantly.

A positive Coinbase premium (Coinbase > Binance) suggests US demand is leading global demand — often considered a higher-quality demand signal than offshore trading.

A negative premium (Coinbase < Binance) is rarer and suggests US sellers are more aggressive, or US demand is lagging global. Historically, extended negative premium has sometimes preceded short-term corrections.

The formula

Premium (%) = (CB_CLOSE − BINANCE_CLOSE) / BINANCE_CLOSE × 100

On the dashboard, this is the PREMIUM column. A value of +0.12% means Coinbase is trading 0.12% above Binance at the close of that candle. A value of −0.08% means the reverse.

Why SignalsDeck shows it but doesn’t vote on it

The premium is context, not a clean directional vote. Here is why:

  1. It is noisy intraday. The premium swings with exchange-specific order flow, momentary liquidity gaps, and stablecoin mechanics. Voting on every tick would produce whipsaws.

  2. It is not symmetric in meaning. A large positive premium during a bull run means something different from the same number during a bear-market relief bounce.

  3. It is most useful as a filter, not a trigger. Experienced traders use the premium to confirm signals from other indicators, not to generate signals on its own.

For these reasons, the mechanical vote uses MACD, RSI, Stochastic, Bollinger Bands, and MA Trend — all of which have clearer binary thresholds. The premium is displayed prominently as a reference data point.

The AI verdict, however, does receive the premium as context. The language model can describe nuances like “Coinbase is trading at a slight negative premium, suggesting US demand is not leading this move” — which a mechanical ±1 vote cannot express.

Where to find it on the dashboard

The Coinbase and Premium columns appear in the main dashboard table for every coin. On the coin detail page you can see how the premium has behaved alongside the OHLC candle — useful for spotting whether the current Binance move is confirmed by US spot demand.

Trading value is estimated from OHLC data. The Coinbase premium compares Binance (USDT) and Coinbase (USD) close prices — both for reference only. SignalsDeck shows market data and educational analysis only. Nothing here is investment advice.
