This is an English translation of the Spanish original, which prevails if the two differ.

Have you spotted a wrong figure, is an instrument or a prop firm missing, or do you have an idea for the calculators? Write to us at sizelotcalculator@gmail.com and we’ll reply as soon as we can.

If you are reporting a mistake in a contract size or in a prop firm’s rules, tell us the broker or the firm and, if you can, the link to its official specification: that way we can check it before correcting it.

We can’t advise you on what to trade or review your strategy: the website only offers calculation tools (as the risk warning explains).

The data you send us is only used to reply to you. More information in the privacy policy.
