OHLC charts

Every trade page on Interstate renders a candlestick chart for the token. Charts combine historical OHLC data with a real-time WebSocket stream so the current candle updates as trades land.

Supported intervals

Candle sizes you can select:

1s · 5s · 15s · 30s · 1m · 5m · 15m · 30m · 1h · 4h · 12h · 1d · 7d

Shorter intervals are useful for launchpad trading and scalps; longer intervals for position context.

Supported timeframes

Historical windows you can load:

1h · 4h · 24h · 7d · 30d · 90d · 180d · 365d

Up to one year of history is available where the token has been trading that long.

The 1,500-point cap

Every chart request is capped at 1,500 data points. That's a hard limit — combinations that would exceed it return a descriptive error.

Practical coverage:

Interval	Maximum coverage
1s	~25 minutes
1m	~25 hours
5m	~5 days
1h	~62 days
1d	~4 years

If you ask for 1-second candles over 7 days, the request is rejected — that would be ~600,000 points.

`optimize=true` — automatic shortening

Passing optimize=true tells the chart service to shorten your requested timeframe automatically so the response stays under 1,500 points. Useful when you want the finest interval possible without manually doing the math.

Example behavior: request 1-second candles over 24 hours with optimize=true → the service returns the most recent ~25 minutes at 1-second resolution instead of rejecting the request.

Real-time candle streaming

Charts are not static. A persistent WebSocket connection streams ohlc_update messages as trades land:

The current candle updates with every new trade — open, high, low, close, volume all change live
When the candle's interval closes, a new candle is started and the closed one is finalized
Historical candles are loaded once on connect as a snapshot; afterwards only deltas are pushed

You can subscribe and unsubscribe from token pairs without reconnecting the WebSocket.

Candle data

Each bar in the response carries:

Field	Meaning
`unix_time`	Timestamp in seconds
`o`	Open price, USD
`h`	High price, USD
`l`	Low price, USD
`c`	Close price, USD
`v_usd`	Volume traded in that candle, USD

All prices are denominated in USD. Perpetuals use TradingView's widget and have their own feed — this page covers spot charts only.

How to read launchpad charts

Early launchpad charts can look extreme. A few pointers:

The 1s and 5s intervals are most useful in the first minutes of a launch — longer intervals collapse early volatility into a single candle.
Wicks often reflect bonding-curve trades across many quick buys; they're not always meaningful price rejection.
Migration from the bonding curve to a permanent pool creates a clean cut in liquidity — the chart continues, but pricing is now AMM-based rather than curve-based. See Pulse lifecycle.
