US500 Lot Size and Pip Value Calculator: Contract Size, Tick Value & Kelly Sizing

Direct Technical Answer

US500 contract size is 1 index CFD per 1.00 lot at $1.00 per point ($50 ES, $5 MES). Typical spread is 0.3 to 0.6 points with a 45 to 85 point daily ATR. For $100,000, lots = 1000 / (stop points × 1), which is 55.55 CFD lots at an 18-point stop.

S&P 500 is the deepest book in the world and the most pinned. 0DTE dealer gamma at 25 and 50 point strikes can hold ES in a 10-point box until 15:50 ET MOC imbalance or 18:00 UTC FOMC blows the pin. 55.55 CFD lots at 18 points is 1% only if you understand $1 CFD versus $50 ES. Copying 55 lots onto ES is a $50,000 idea, not a $1,000 idea.

$1 CFD, $5 MES, $50 ES: do not mix them

Prop US500/SPX500 CFDs are often $1.00 per point. MES is $5. ES is $50. 55.55 CFD lots at 18 points is $1,000 at $1/point. 55 ES lots would be $50 per point × 55 × 18 = $49,500. That conversion error is the career-ending version of "S&P lot size."

Spread 0.3 to 0.6 points, the tightest US index. ATR 45 to 85 points, smaller in points than NAS100, which is why the 1% stop is 18 points and lots look huge on a CFD. Handles 5800, 5850, 5900 (25/50/75/00) are gamma walls, not just round numbers.

Gamma pins, FOMC, and the 15:50 ET MOC

0DTE options pin ES around big 50-point strikes. Mean reversion to HVN/POC works until it does not: FOMC at 18:00 UTC and the 15:50 ET market-on-close imbalance. Trading a 6-point scalp into FOMC with 55 lots is a pin that got fired.

Cash hours 13:30 to 20:00 UTC are the product. connect your MT5 account to Venasri and treat 15:50 ET and FOMC as blackouts even when the rest of the day was a 12-point coil.

55.55 CFD lots at 18 points, or 11 MES

At $1/point: lots = 1000 / 18 = 55.56, stored as 55.55 at 1%, 27.77 at 0.50%. At $5 MES, 1% is 11.11 micros. At $50 ES, 1% is 1.11 minis. Put the correct tick in the Half-Kelly Lot Size Calculator & Equity Guard.

Scalp 6 to 12 points only when a gamma wall is obvious and spread is 0.3. Intraday 14 to 24. Swing 38 to 65 at ~15 CFD lots. If NAS100 is open, US500 does not get 27 extra lots. Same beta, tighter pin.

Trade the pin or the FOMC, not both with 55 lots

Intraday: fade 25/50 strikes toward POC with 14 to 24 point stops during RTH, 27.77 lots. Event: flatten into FOMC and MOC. Overnight: MES-equivalent size only.

Confirm strike wall, unused Nasdaq/Dow budget, and 15:50/FOMC clear on the Pre-Trade AI Confluence Checklist. US500 is a precision index. The 55-lot number is a CFD optical illusion, not an invitation.

Frequently Asked Questions: US500 Lot Size and Pip Value Calculator: Contract Size, Tick Value & Kelly Sizing

What is US500 pip value per 1.00 lot?

Typically $1.00 per point on prop CFDs, $5 on MES, $50 on ES. A 18-point stop on 55 CFD lots is $1,000. On 1 ES it is $900. On 11 MES it is about $990. Match the contract.

What lot size is 1% of $100,000 on US500?

55.55 CFD lots at 18 points and $1/point, or 11 MES, or 1.11 ES. Use 27.77 CFD lots at 0.50%. If your broker's US500 is $2 or $5 per point, recompute; do not blindly type 55.

How do I convert ES size to a prop CFD lot?

ES $50/pt ÷ CFD $1/pt = 50 CFD lots per 1 ES. MES $5/pt = 5 CFD lots per 1 MES. 1 ES ≈ 50 CFD lots ≈ 10 MES for the same dollar point risk.

Why is the US500 stop only 18 points?

ATR is 45 to 85 points and gamma often pins a 10 to 20 point box. 18 points is 1% reference inside that body. FOMC days need 38 to 65 point swing stops and a third of the lots.
