Given that it is necessary to close a deal with a result of +1 point, it makes no sense to keep the position open for more than 1 hour (we will discuss the issue of binary options expiration later, because this is the thinnest point in binaries). But first, we determine that with the current high market volatility, the optimal position retention time is 15-30 minutes, so we will do all the other constructions based on this parameter.
