Renewable forecasting for traders: why the forecast is the edge
Short-term power prices are set by renewable output. A desk that knows tomorrow's solar and wind feed-in a few percent better than the market has an edge in every day-ahead auction and intraday ramp; a desk that does not is trading against it. Building that forecast in-house means weather-data licences, satellite feeds, asset telemetry and a data-science team — and the model still has to be maintained around the clock.
SAMAWATT sells the output of that stack as an API: asset-level solar and wind forecasts, bidding-zone aggregates and price forecasts on the same 15-minute horizon our own trading engine uses.
How the trading API and execution-as-a-service connect to your desk
Two integration levels: pull forecasts into your own strategies, or send signals and let SAMAWATT's auto-trader execute. Both run on the same documented REST and streaming API with sandbox keys.

- 2Run your strategyFeed the forecasts into your own models or use SAMAWATT's signal library; your P&L and risk limits stay on your side.
- 3Execute through the auto-traderOrders are routed through SAMAWATT's ISV-certified connections to EPEX SPOT and ETPA with sub-15-minute latency.
- 4Monitor and reconcileFills, positions and exchange reports are returned via the API and reconciled against your trade capture system.
Algorithmic intraday trading: speed, spreads and ancillary access
Intraday margins live in the minutes after a forecast changes. Managed exchange connectivity with sub-15-minute signal-to-fill latency lets algorithmic strategies capture ramps and shadow events before the spread closes. Reserve and imbalance markets, normally closed to desks without prequalified assets, become accessible through SAMAWATT's aggregated portfolio, adding ancillary revenue to a pure spot book.
Desks pay a data subscription and a per-MWh execution fee; there is no exchange membership, connectivity maintenance or 24/7 operations cost on your side.
