Places 1 to 10 identical one-tick digit contracts at the same moment, straight from your browser to Deriv. This site has no server: your token is kept only in this tab and is forgotten when you refresh or close it.
Create a Personal Access Token at developers.deriv.com with only the Trade scope. Delete it on Deriv when you finish.
Each contract lasts one tick. Past results do not predict the next digit. Try a demo account first.
