A highly incompetent company. Do not consider them as a broker at all.
With them on IIS it is possible to buy only domestic securities (for comparison at all other brokers it is possible to buy foreign, which are on the Moscow and St. Petersburg stock exchanges).
In 2018 for this reason I asked them to transfer my IIS to another broker, and ATON just closed my account.
Asked several times about keeping the term - I was told it would be fine.
When it came to getting a deduction at the tax office, they refused.
Now I am told by ATON - "well, you had no money there". And at the time of the transfer, of course, it was impossible to do it.
In general, the impression of ATON - is a scam, no competence there.
I do not recommend anyone to work with them.
