An automated trading system you buy once — not rent forever
Most NinjaTrader systems are subscriptions: a monthly fee, every month, for as long as you trade. SI-Trader is sold the old way — $569 USD, one time — and this page does the honest math on both models.
The math
| SI-Trader (one-time) | Typical subscription system | |
|---|---|---|
| Up front | $569 once | First month: often $100–$200 |
| After 6 months | $569 total, forever | $600–$1,200 and counting |
| After 2 years | Still $569 | $2,400–$4,800 — and you own nothing |
| If you stop paying | Nothing to stop — it's yours | The system switches off |
| Feature tiers | None — every buyer gets the whole system | Often gated behind higher tiers |
The subscription column is a pattern, not a quote of any single competitor — check the current terms of any system you are considering, because the model, not the marketing, decides what you pay over a trading career.
When a subscription is honestly the better deal
Renting is not always wrong. If you want to trial a system for one month before committing, a subscription's low entry price is rational — as long as you actually decide at the end of the month. Subscriptions also suit services with real ongoing costs, like hosted data or a staffed signal desk. What they do not suit is a finished piece of software sitting on your own computer: there, the monthly fee buys you nothing new after month one.
Why SI-Trader is sold this way
- It runs on your machine. Activation is verified locally; there is no vendor server in your trading loop to pay for monthly.
- One price, whole product. All 50 edges, the guide in three languages, and the instrument templates are in the single purchase — no unlock tiers.
- No renewal ambush. The price at checkout is $569.00 with tax included, and nothing is ever charged again.

Risk disclosure: Trading futures involves substantial risk of loss and is not suitable for every investor. Past performance — including any backtested or hypothetical results — is not indicative of future results. SI-Trader is software, not financial advice, and buying it does not guarantee profits. Only trade with capital you can afford to lose.
