If you are doing ultra-short-term transactions, you can open an account in a different place, so you may get the lowest handling fee, but remember, there is no minimum, only lower. You can ask to talk to their manager directly, and then tell them that you are doing ultra-short-term work and the amount of funds is not bad. I hope they can reduce the handling fee. Everyone is pursuing average income.
If you don't do ultra-short-term transactions, don't open accounts in different places, otherwise you won't enjoy more services. It will be much more convenient in case something happens.
In fact, it is normal to open an account in a different place, and your funds should still be transferred at your local bank. This requires you to consult their business.
There is no problem in other aspects. At present, all funds are deposited by third parties, and the CSRC is relatively strict, which is generally no problem.
In fact, these are not particularly important, as long as they are not fake futures companies (referring to disguised futures, spot or illegal financing). The key is your operation method and your personal mentality. Don't trust anyone but yourself!
My friend, "from the perspective of game theory", if a person wants to get excess returns, he must have at least one resource that others don't have, because if others have his resources, then others will adopt his investment strategy and compete for excess returns until the excess returns disappear.
I hope you can succeed! !
