FBS has got no restrictions on the trading method, and you can have a position opened as log as you want.
You just need to make sure that you have got enough margin to support all your open positions, as swaps charges and spread condition may affect your margin requirement.
FBS is a STP broker
When it comes to making profit with FBS, it might be the best choice for the traders and FBS is a STP broker and there is no conflict of interest between FBS and traders.
STP stands for Straight Through Processing, and this means that the orders from traders are directly sent to the real FX&CFD markets without FBS hedging the orders with its own funds.
This may not affect your trading conditions though, this decide either the broker support traders to make profit or not.
Simply, if a broker is a market maker(not STP), it may restrict some trading methods and even cancel profits of traders to avoid making losses for them.
All trading methods available
Like already said, FBS does not restrict any trading methods so you can do hedging, scalping, EA trading and etc.
