Direct Technical Answer

US500 on a $100,000 prop CFD account is $1.00 per point per lot ($5 MES / $50 ES), 0.3 to 0.6 point spreads, and a 45 to 85 point daily ATR. Lots = 1000 / (stop points × 1) = 55.55 lots at an 18-point stop, or 27.77 lots at 0.50% risk.

S&P prop breaches are conversion and pins. Someone types 55 lots because a blog used a $1 CFD, but the firm's US500 is $5 a point. Or they fade a 5850 gamma wall with 55 lots into FOMC and the pin becomes a 40-point trend. 0DTE makes this index look like free mean reversion until 15:50 ET or 18:00 UTC proves it is not.

55 lots is only 1% on a $1 tick

Confirm dollars per point before the first click. 27.77 lots at $1 lose $27.77 per point. An 18-point stop is $500. A gapped 40-point FOMC fill is $1,110. At $5/point those numbers quintuple. Read the spec, then size.

connect your MT5 account to Venasri and store the contract tick in Equity Guard. Wrong tick value plus 55 lots is how a "conservative S&P" account ends in one statement.

Respect the pin, flatten the event

25 and 50 point strikes are real. Fade them during RTH with 14 to 24 point stops when HVN agrees. Do not fade them at 15:45 ET or into FOMC. MOC imbalance at 15:50 ET can run 15 points in a minute through a 6-point scalp stop.

Overnight ES is a different market. If weekend holding is banned, flatten Friday. CPI 8:30 AM ET still gaps the pin before cash. That is a news blackout, not a "small ATR" exception.

One beta budget across ES, NQ, YM

US500 + NAS100 + US30 = 0.50%. The Half-Kelly Lot Size Calculator & Equity Guard must use this symbol's tick, not Nasdaq's $1 with Nasdaq's 70-point stop.

Intraday 14 to 24 points at 27.77 CFD lots ($1). Swing 38 to 65 at ~15 lots. Scalp 6 to 12 only on a visible wall with 0.3 spreads. FOMC size is 10 lots or flat.

US500 checklist: tick confirmed, wall or trend, no MOC/FOMC, one index

Require verified $/point, RTH session, unused Nasdaq/Dow budget, not 15:50 to 16:00 ET, not 30 minutes around FOMC, 18-point-class stop or a deliberate 38-point swing reduction, 50-point strike mapped.

Load that on the Pre-Trade AI Confluence Checklist. Manual Trade Guard attaches 18 points on fill; 55 CFD lots at $1 (or 11 MES) do not get a human-delay stop on a pin break.

Frequently Asked Questions: US500 Trading Strategy and Contract Guide: Institutional Zones, Lot Sizing & MT5 Automation

What US500 size should a $100,000 challenge use?

First confirm $1 vs $5 vs $50. On a $1 CFD, 27.77 lots at 18 points (0.50%). 55.55 lots is a 1% ceiling for pinned RTH only. On MES, about 5.5 micros at 0.50% and 18 points.

Should I fade 0DTE strikes on a funded account?

Yes during regular hours when POC agrees and FOMC/MOC are not near, at 27.77 lots max. No into 15:50 ET or FOMC. Pins that break become 38-point trends fast.

Can I run US500 and NAS100 together?

Only inside one 0.50% beta budget. 27 S&P CFD lots plus 7 Nasdaq lots is two expressions of the same 8:30 AM CPI print. Pick the tighter book (often S&P) or the bigger trend (often Nasdaq), not both full size.

Why did my small ATR still breach daily loss?

Either the tick was not $1, or an 18-point stop filled at 40 on FOMC/CPI, or you stacked indices. ATR 45 to 85 is average, not a cap. Events print the cap.
