This page outlines caching durations for various GM Backend API endpoints, establishing performance parameters while balancing freshness requirements.

​
Markets

Endpoints: Get Market Data for All Supported Assets | Get Market Data for an Asset
  • Cache Duration: 1 minute
  • Market data is relatively static. A 1-minute cache strikes a balance between performance and freshness.

​
OHLC

Endpoint: Get OHLC Data for an Asset
  • Cache Duration: 1 second
  • Data Delay: Underlying OHLC data may itself be delayed by up to 5-10 seconds
  • Effective Lag: Up to 11 seconds
  • This design reduces load while ensuring users have access to consistent, batched candlestick data.
For real-time OHLC updates, see OHLC Streaming Endpoint.

​
Latest Prices

Endpoints: Get Current Prices for All Supported Assets | Get Current Price for an Asset | Get Enhanced Prices for All Supported Assets
  • Cache Duration: 1 second
  • Price queries are the most latency-sensitive. The cache is kept minimal to support near-real-time pricing while still providing performance benefits.
For real-time price streaming updates, see Price Streaming Endpoint.

​
Trading Limits

Endpoint: Get Trading Limits
  • Cache Duration: None
  • These values are critical for risk management and must always reflect the latest state.

​
Session Limits

Endpoint: Get Session Limits
  • Cache Duration: 1 minute
  • Session limits are relatively static, so a 1-minute cache strikes a balance between performance and freshness.

​
All Metadata

Endpoint: Get Metadata for All Supported Assets
  • Cache Duration: 5 minutes
  • Metadata is relatively static, so a 5-minute cache strikes a balance between performance and freshness.

​
Shares Multiplier

Endpoint: Get Shares Multiplier History for an Asset
  • Cache Duration: 1 second
  • Shares multipliers change infrequently, but a 1-second cache supports near-real-time discovery of the shares multiplier change while still providing performance benefits.

​
Portfolios

Endpoints: Get All Portfolios | Get a Portfolio
  • Cache Duration: None
  • The API refreshes portfolio data in the background approximately every minute. The timestamp field of each portfolio shows the time of its last refresh.

​
Default Behavior

Unless otherwise specified, all GET endpoints default to:
  • Cache Duration: 1 minute
  • This ensures consistency across the API and reduces the need for endpoint-specific caching rules.
