Research and evidence. Every composite pane live, the full indicator catalog, and durable backtest evidence that Trade Plans, Forward Evidence and Edge Atlas can cite.

Work Meridian performs continuously on your behalf — the optimizer, automations that run around the clock, and the only tier that touches real capital.
The first 100 Pro accounts pay $9 a month, locked at that price for as long as the subscription stays open — through every future price rise. Same Pro plan, same 500 credits a month.

Your plan decides what you can do. Credits pay for the work Meridian runs on its own machines for you — server backtests, Edge Atlas, the optimizer, and automations that keep running while you are away. Anything that computes on your own device is free and always will be. Every tier receives an allowance each month; paid tiers can buy more.
One-time purchases, available to Pro and Quant. Every pack costs more per credit than a subscription’s included allowance — subscribing is always the better deal, and it should be.
Everything that helps you understand a market and prove a claim about it — realtime state, the full catalog, durable backtest evidence, Edge Atlas, Forward Evidence — lives in Pro.
The optimizer, automations that run around the clock, and anything that touches real capital sit in Quant. They are the tiers of the product that consume our worker pool continuously.
A backtest that runs in your browser costs us nothing, so it costs you nothing. A run on our workers is durable evidence everything downstream can cite — and that is what credits pay for.
Additional 24/7 capacity is available to Quant subscribers and is managed from Settings. An extra slot reserves concurrency only — it grants no additional credits.
Meridian is analysis software. It reports market state; it does not tell you what to buy or sell, and nothing it produces is investment advice.
