Net movement of this coin on and off centralised exchanges, across every chain we index. Coins moving ONTO an exchange are being positioned to sell; coins moving OFF are going to self-custody or staking.

Coins moving ONTO an exchange usually means someone is getting ready to sell them. Coins moving OFF usually means they are being held for longer. One large move in a single hour is often just one person shuffling funds; the same direction repeating over days is the signal worth acting on.

Exchange netflow is a well-known on-chain indicator: sustained outflows shrink the supply available to sell and tend to precede strength, while sustained inflows do the opposite. Reserve depletion strategies take positions when exchange balances fall to multi-year lows. It is a slow signal — better for framing a position over weeks than for timing an entry.

Design a new swing strategy for PYUSD driven by exchange flows from /api/v1/on-chain/exchange-flows/PYUSD. This is a slow signal, so define a holding period in days or weeks and say what invalidates the trade rather than using a tight stop. Validate against the exchange_flows block of /api/v1/backtesting/daily-snapshots/{date} plus daily bars from /api/v1/backtesting/klines, and report whether the signal survives transaction costs.

Exchange flows are archived per chain in the exchange_flows block of /backtesting/daily-snapshots/{date}. It is a daily series rather than intraday, which suits the signal — netflow is a multi-day read, not an entry trigger.

Using CryptoDataAPI, test exchange netflow as a signal for PYUSD. Pull the exchange_flows block from /api/v1/backtesting/daily-snapshots/{date} across the archive and daily price bars from /api/v1/backtesting/klines. Compare forward 7d and 30d returns after sustained net outflows versus sustained net inflows. Report whether the difference is large enough to trade after costs.
