S&P 500 ETF (SPY) leverage simulator

50x survived every one of the last 30 sessions on SPY. Nothing above it did. Set a wager and a multiplier up to 1000x on S&P 500 ETF below.

Verdict

At 100x, a 1.0% move against you ends the position. SPY moved that far on 8 of the last 90 sessions.

Warning

20x is the ceiling, and it is not a safe one. Every step up shrinks the move that closes you out: 1.0% at 100x, 0.2% at 500x.

Where you can trade it
Moon lists SPY, and the code MARKET applies on the way in. Opening costs 1 per cent of your wager at every level on the range.Availability checked 2026-08-27.

Why it moved

SPY put in a 0.55 per cent fall inside its 0.75 per cent normal day, quiet enough that no source search was run.

What SPY did to leverage in 6.5 hours

You had 0.35 per cent down to work with on SPY over 6.5 hours, $760.12 to $757.42. Your $100 on the SPY short is $99.71 at 2x and $134.48 at 100x. 3 of 18 SPY multipliers did not finish the 6.5 hours, the last of them 200x long after 81 minutes. The best SPY survivors were 100x long and 1000x short. None of that touches the 1 per cent of stake the 100x SPY round trip already took, which 0.01 per cent of price squares, near 1.3 per cent of a typical session.

Where S&P 500 ETF has been trading

$757.42 is the last SPY print, down 0.44 per cent for the session and down 1.12 per cent on the week. Over three months SPY is up 2.76 per cent. SPY has closed lower 2 sessions running.

How far SPY moves in a session

SPY runs 12.5 per cent annualised volatility over 30 sessions against 12.8 per cent over 90, which by leveraged standards is a bond fund with a ticker. An ordinary SPY day swings 0.79 per cent either side of flat, and at its worst SPY fell 2.83 per cent below an open in the last 90 sessions.

The multiplier SPY actually survives

Run the last 30 SPY sessions and 50x is the most you could have held without being closed out, with your liquidation 2 per cent away. Stretch the SPY window to 90 sessions and it drops to 20x. 0.4 per cent of one-minute SPY bars span the entire 1000x liquidation distance, on a median bar of 0.0106 per cent.

Max loss distance is one part in the leverage, because Moon closes a wager once it has lost the wager and documents no maintenance buffer. Hit count is the number of the last 90 sessions where the low fell that far below the session open, i.e. where a long opened at the open would have reached its max loss price intraday. Cost is Moon's 1% opening fee, charged on the wager and not on the exposure, so it does not change from one multiplier to the next. A rolling fee applies every 8 hours at a rate Moon does not publish and is not included.

What SPY costs you to open

You pay 1 per cent of your wager to open SPY and nothing on your exposure, so $100 down costs $1 at 2x and $1 at 1000x. What changes is your room, and an average SPY session covers the 100x liquidation distance 0.8 times over. Carry SPY beyond 8 hours and you pay again at a rate Moon gives no figure for, which is why the 1 per cent is a floor.

SPY leverage questions

What multiplier is realistic on SPY?

50x, the highest SPY multiplier that avoided liquidation on every one of the last 30 sessions. A 2 per cent move against you closes the SPY wager.

What does opening a wager on SPY cost you?

1 per cent of your SPY wager, the same at 2x as at 1000x. Hold SPY past 8 hours and a rolling fee is added at a rate Moon does not publish.

Does 1000x make sense on SPY?

Your max loss price sits 0.10 per cent from entry, which SPY covered on 74 of the last 90 sessions. The length of your SPY hold settles it rather than the 1 per cent fee.

Before you take this to Moon

Everything above is derived from independent third-party market data. Moon prices its own book: the reference price, the spread it quotes, its fee schedule, its funding rate and its liquidation engine are all Moon's, and they will produce a different number from this page.

Every multiplier above is measured on SPY's own last 30 sessions rather than on a market average, so it tells you how leverage behaves on SPY and nothing else. Price your own SPY size on Moon against those 30 sessions before you commit to it.

What this simulator is

Prices come from Twelve Data, an independent market-data vendor, and are indicative. Moon's own reference price, spread, fee schedule, funding and liquidation rules will produce a different result. No money is staked here, no order is routed, and no position exists on any platform. At 1000× leverage a 0.01% difference between this chart and Moon's settlement feed moves the position value by roughly 10% of the stake, so treat every number below as an illustration of mechanics rather than a forecast of outcome.

Leverage arithmetic used

Exposure = stake × leverage. Long P/L = exposure × (mark − entry) ÷ entry. Short P/L = exposure × (entry − mark) ÷ entry. Entry takes the ask for a long and the bid for a short; closing does the reverse, so the spread is charged on the round trip. Liquidation triggers when equity falls to the maintenance margin, i.e. at an adverse move of (1 − leverage × maintenance rate) ÷ leverage.

Jurisdiction

Leverage caps, incentive bans and product classification differ by country. Retail CFD rules in the EU cap equity leverage far below the levels shown in this demo and restrict monetary incentives such as rakeback, so the referral block and the maximum selectable leverage must be gated per market before any page goes live. 18+. Trading leveraged products carries a high risk of losing your capital.
