First: theoretically, even the slowest one should be faster than manual one. However, there is a disadvantage in this, that is, the current price and market price are still over-priced. Because when the market fluctuates violently, it is very likely that documentaries will not be sold. This needs to be taken into account.

Second: the speed of the documentary system is also related to the code of your system, whether it is the optimal code.

Third: Even your documentary system uses a very different network. The better the network speed, the faster the order will be transmitted to the exchange, and the greater the probability of transaction.

Fourth, it is closely related to the futures company where you open an account. When a futures company submits your order, if a small futures company needs to save costs, the server may be poor or small, but at a certain point, when a large number of orders are submitted, there are likely to be some problems such as congestion and delay, which also need to be considered.
