Lot Size for US30 and NAS100: Indices Are Different

The right lot size for US30 depends on your broker more than on the index, because brokers set different contract sizes for the same Dow Jones CFD.

One Index, Three Contract Sizes

On forex, 1 lot is almost always 100,000 units. On indices there is no standard. Depending on the broker, 1 lot of US30 (or NAS100 / USTEC) may be worth:

Same trade, same $100 risk - and lot sizes from 0.10 to 10.00. Copying a lot size from a video or a signal on indices is how traders end up risking 10 times what they meant to.

Find Your Index Point Value

In MT5: right-click the symbol in Market Watch > Specification. Look at contract size, tick size and tick value. Tick value ÷ tick size = money per point for 1 lot.

Or skip the math: the ATC Position Tool and Trade Manager MT5 reads these values from your broker. Place the trade, drag the stop 100 points away, and it shows the lot size for your risk, already rounded to the broker's lot step.

Quick Tip

After switching brokers or symbols (US30 vs US30.cash, NAS100 vs USTEC), always place one trade plan on the chart before trading. If the lot looks very different from what you are used to, the contract size changed - not the market.

FAQ

How much is 1 point on US30?

What is the best lot size for Nasdaq (NAS100)?
