What brokers offer demo accounts that allow you to buy custom lot sizes?

Basically the title. I use ToS for options trading but their PaperTrade application only allows you to buy in the predetermined lot sizes (micro, mini, macro, etc.). This is kind of a problem because I want to replicate the conditions of accounts with only minimal amounts of initial funding so that I’m extra prepared not to blow my accounts when I put a reasonable amount of money in it. Anyone got any suggestions? Thanks in advance.

I use Forexchief live account. I also use the demo once in a while. Yes, you can choose your lot size before placing a trade. The platform is Mt4 or mt5.

I’ve heard of that broker before. Everyone I know says they scam and there’s plenty of online reviews that corroborate that sentiment. Thanks for the recommendation but I’m steering clear of them for now.

Oanda.

You can trade ANY number of units — one unit, ten units, 73 units, 502 units – or you can trade the typical 1,000 units (micro-lot), 10,000 units (mini-lot), etc.

Oanda’s demo accounts and live accounts all offer this feature.

Thanks! I just signed up for a demo account.`
