European power markets are full of mispricings waiting to be found — renewable intermittency, cross-border arbitrage, intraday volatility. Help us build the meta-forecast that exploits all of them. Build and backtest free. When you're ready, €199 unlocks a 28-day evaluation — pass it and trade a funded €10,000 account, keeping 70% of profits.
Your €199 unlocks a 28-day evaluation on a €10,000 simulated account. Pass and you're funded — no recurring fees, no data charges. The fee funds trader capital, data licenses, and infrastructure, and keeps the evaluation serious.
You never put up trading capital. Your algorithm trades a simulated €10,000 account against real market data — backed by Voltra's own reserves. Your only financial exposure is the €199 evaluation fee.
Voltra Trading is a registered technology and education platform in Copenhagen, Denmark. Real founders. Real legal entity. Look us up.
Your algorithm runs on your own machine, never on our servers. You submit only the trading signals it produces — direction, size, market, price. Your code, your edge, your IP never leave your laptop. We literally cannot read it.
No capital required. No experience required. No gatekeeping. Just prove your algorithm works.
Over five years of European power — prices, renewables, flows, weather, fuel, carbon. 123 raw features, hourly resolution, 2021-present. Every signal intact.
Backtest on historic data, forward-test against live European power in the free sandbox. Iterate until you have real edge.
28 days of live European prices, scored on five criteria to qualify. Top-ranked traders each challenge earn funded accounts.
Trade €10,000, scaling up to €250,000 as your track record holds. Keep 70% of profits, paid to your bank at month end.
No exchange membership. No trading capital required. No regulatory setup. Just Python and the time to build something that works.

Flat split on every euro of profit. Paid monthly by SEPA bank transfer. No caps on earnings.
Not forex. Not crypto. Real European power markets with genuine structural inefficiencies — day-ahead vs intraday spreads, cross-border arbitrage, renewable intermittency.
You provide the algorithm. We provide the infrastructure, data, and funded account. No exchange memberships, no capital, no desk required.
Funded accounts start at €10,000 and scale as your rolling metrics hold up. Clean Sharpe, clean drawdown, sustained alpha — up to €250,000.
We never see your code. Your algorithm runs on your own machine — you submit only the signals it generates, never the logic behind them.
We launch where the hourly day-ahead auction is deepest and the renewable forecast-error signal is richest. Additional zones open as we grow.
Hourly DA auction, simulated fills at the cleared price. One prediction per hour, 24 hours per day. This is the tournament you submit to.
Continuous intraday products and 15-minute granularity. Shorter horizons, faster feedback, separate leaderboard.
Deploy a funded strategy as a live-dispatch model for battery and flexible-load operators. Track records on the leaderboard feed into allocation.
Power markets misprice the spread between the T-1 day-ahead forecast and what actually clears. Recurring edge comes from wind and solar forecast error, load forecast error, cross-border flow shifts, and gas and carbon prices lagging into power. Your model doesn't need to know which driver it's capturing — it just needs to find them in the data.
Five pass criteria plus a hard drawdown cap, measured over your 28-day evaluation window. Clear all five by day 28 without a drawdown breach and your account converts to funded. Same rules then govern scaling on your rolling funded performance.
Risk-adjusted returns on your daily P&L series. Measures consistency, not raw profit — a few huge days alongside a string of losers won't clear the bar.
€1,000 total loss cap plus a €500 daily cap during evaluation. Once funded, the total becomes a trailing cap that locks at your €10,000 starting balance once equity passes €11,000.
Your cumulative net P&L has to end above zero. No minimum amount — but an account that never turns a net profit won't scale, and won't pay out.
Returns independent of the consensus — the unique signal your algorithm contributes on top of the crowd. Copies of consensus models don't scale here.
Days where at least one delivery hour actually filled. Pure forecasting without committing to bids doesn't clear the bar — you need to trade, not just predict.
Average error on your price forecasts against actuals, averaged across DA and balance. Keeps the incentive on forecasting accurately — not just picking a direction.
Your €199 is a one-time fee for the 28-day evaluation — no subscriptions, no data charges. Meet all five criteria without a drawdown breach and your account converts to funded on day 29, with the same rules applied on a rolling basis. Fail and you can retake after a 24-hour cooldown.

European power is one of the hardest forecasting problems in the world. Weather, policy, fuel, cross-border flows, renewable intermittency, and thousands of dispatch decisions collapse into a single price every hour. No desk, no quant team, no single institution prices it perfectly — and that is exactly why we built Voltra.
The best algorithm for European energy will not come from one office in Frankfurt or one quant team in London. It will come from hundreds of independent minds, each finding a small edge the others missed, stacked into a forecast that no individual could build alone. Every trader on Voltra is a contribution to that. Every payout we make goes to the ones whose edge survives.
The €199 evaluation fee funds what you actually compete for: the funded-account capital pool itself, premium market-data licenses that sharpen the edges available to everyone, and the infrastructure that keeps the platform running. It is also the filter that keeps the platform honest — real skin in the game means the traders here are the ones building seriously, not gaming the evaluation for free attempts. We grow when our traders grow. That is the only arrangement that makes sense when the product is a collective intelligence.
