How does the contract size change your US30 and NAS100 lot size?

The single most common sizing mistake on FTMO, FundedNext, and The5ers happens when a trader switches between a broker where 1.00 lot = 1 index contract ($1/pt) and a broker where 1.00 lot = 10 or 100 contracts ($10/pt or $100/pt). Entering 5.00 lots on a 50-point US30 stop risks $250 on a 1-contract specification, but risks $2,500 on a 10-contract specification—the whole 5% daily loss limit of a $50,000 account on a single trade.

GER40, UK100 and JP225 move one euro, pound or yen a point per contract. The calculator converts that to dollars at example rates ($1.08 per EUR, $1.30 per GBP, $0.0067 per JPY), not live rates. Check the point value in your broker's contract specification: it is the authority.

Which tools size gold, index futures and forex positions?

Method and privacy

Method: Dollar value per 1.0 index point per 1.00 lot = contractSize × usdPerIndexPointPerCfd ($1.00 on a 1-CFD lot, $10.00 on a 10-CFD lot). Risk per 1.00 lot = (stopPoints + spreadPoints) × dollarPerPointPerLot + commissionPerLot. Recommended lots = floorToLotStep(riskUsd ÷ riskPerOneLot). Check MT5 Specification → Contract Size before placing an order.

Common questions

How much is 1.00 lot of US30 or NAS100 worth per 1 index point?

It depends entirely on your broker's or prop firm's MT5 Contract Size specification. At 1 CFD per 1.00 lot (FTMO, FundedNext, Five Percenters), 1 index point = $1.00 per 1.00 lot ($0.01 per 0.01 lot). At 10 CFDs per 1.00 lot (some offshore/multi-asset CFD feeds), 1 index point = $10.00 per 1.00 lot—making the exact same 1.00 lot 10× larger.

What is the difference between 1 index point and 1 MT5 point/tick on US30 or NAS100?

An index point is a 1.00 full integer move in the index price (for example, US30 moving from 43,200.00 to 43,250.00 is 50 index points). Because MT5 quotes indices to 1 or 2 decimal places, MT5's crosshair and order window display 50 index points as 500 points (1-decimal quote) or 5,000 points (2-decimal quote).

How do I check my broker's US30 or NAS100 Contract Size in MetaTrader 5?

Right-click US30 or NAS100 in MT5 Market Watch, click Specification, and read the Contract size row. If Contract size = 1, use the 1 CFD / lot preset ($1/pt/lot). If Contract size = 10, use the 10 CFDs / lot preset ($10/pt/lot).

How do I size US30 or NAS100 safely inside a 5% prop firm daily loss limit?

Keep your per-trade risk at 0.5% to 1.0% of starting balance (10% to 20% of a 5% daily loss allowance) and include the index spread inside your stop distance so an opening bell spread expansion at 09:30 ET does not consume a full 1R loss.

Limits and trading risk

These tools calculate from your inputs, supported historical records or explicitly labelled teaching examples. They do not verify a live account, predict future returns or confirm that a broker or prop-firm rule has been met. Missing costs, floating losses and changed market conditions can materially change outcomes. Trading can lose the capital committed to it; check the stated method and your account specifications.
