Compared with GreeksLab
A GreeksLab alternative with no tier caps
Volatlas backtests the same 0DTE structures on a desktop engine, where the legs, the exit rules and the grid size are bound by your cores rather than by a plan. Market data comes from your own vendor, so the root list is whatever you buy.

Side by side
What each one does with a backtest
| Volatlas | GreeksLab | |
|---|---|---|
| Price | $49 once, rising to $99, with lifetime updates. The licence stays yours at the price you paid. | €49 a month on Premium or €99 a month on Power, priced in euros, so a dollar card also pays the exchange rate. |
| Free tier | None. A thirty day refund covers the same ground. | One concurrent backtest on 2022 data, unlimited for the first thirty days and no card asked for. |
| Market data | Bought from your own vendor and billed to you. $40 a month on ThetaData, cancel-anytime, or metered on Databento. | Included, with nothing to buy, install or configure. |
| Underlyings | Any root your data vendor sells. SPX, SPXW, XSP, NDX, RUT, SPY, QQQ, IWM and single names load the same way. | SPX, which the product is built and tuned for. |
| History depth | Whatever you pull. Databento's OPRA history opens in 2013, ThetaData reaches four to twelve years by tier. | Since 2012 at 1-minute on both paid tiers, 2022 alone on the free tier. |
| Resolution | 1-minute quotes, with stops and targets interpolated to the second inside the bar. | 1-minute. |
| Strategy complexity | Unmetered. Legs, strike selectors by delta or offset, entry schedule, profit target, stop, time exit, DTE exit and days-in-trade all come with the licence. | Two positions per strategy and four rules per position on Premium, four and eight on Power. |
| Concurrent runs | As many as your cores carry, and a sweep grid of up to 10,000 cells runs in parallel as one job. | Two at a time on Premium, five on Power. |
| Fills | Halfway between the mid and the side you are crossing to, plus commission on every contract, charged by default. | Slippage and commission are configurable inputs. |
| Margin | Reg T, uncovered rules included. An entry the account cannot carry is skipped and counted rather than filled. | Not stated in the public documentation. |
| Platform | macOS and Windows desktop, signed and notarized on Mac, computing on your own cores. | Web, so any operating system with a browser. |

Volatlas rows are the $49 licence plus data billed to your own account, either four months a year of ThetaData’s $40 cancel-anytime tier or a year of 1-minute SPXW quotes on Databento at about $271 including contract definitions, metered, so it moves with what you pull. GreeksLab rows are its published monthly prices over the same thirty-six months, in euros. Prices shown as of August 2026.
Which to pick
Where Volatlas lands
- The study reaches past SPX, to XSP, NDX, RUT or a single name.
- A strategy wants more legs or more exit rules than a tier allows.
- You sweep parameter grids and want the grid bound by your cores rather than by a plan.
- Research arrives in bursts and you would rather not pay through the quiet months.
- You want the trade log, equity curve, stats and sweep grid out as CSV.
- You already hold a ThetaData or Databento subscription.
Common questions
Switching and setup
- Can I bring a GreeksLab strategy across?
- There is no import. You rebuild it in Volatlas, which for a 0DTE rule set means the legs, the entry time and frequency, the strike selectors and the exits. An iron condor takes a couple of minutes.
- GreeksLab includes the data. Why buy it separately?
- Bundled data is the part of a subscription that keeps billing when you are not researching, and it is what fixes the root list at SPX. Buying it yourself means the bill stops between studies and the chain covers whatever your vendor sells.
- Which one is cheaper for a single 0DTE question?
- GreeksLab, if the question fits inside its free tier or one Premium month and only concerns SPX. Volatlas pays back when the research recurs, when a strategy outgrows the tier caps, or when the study moves to a root GreeksLab does not carry.
- What does the data cost on top of the licence?
- On Databento a year of 1-minute SPXW quotes runs about $265, plus about $8 of contract definitions, metered and billed to your own account. ThetaData starts at $40 a month for four years of history and is cancel-anytime. The data cost calculator prices your own window on both.
- Does the research survive a cancelled data subscription?
- Yes. Everything you pull is cached as Parquet on your own disk and replays with no vendor involved. Cancelling costs you new history, not the studies you have already run.
- Does Volatlas place trades?
- No. You build, test and sweep in Volatlas and trade wherever you already trade.
One engine, every root
A licence bought once, lifetime updates, and a seat that moves between machines from inside the app. The strategy is as complex as the idea needs, and the grid is as wide as your cores allow.
