I'm based in the US and very new to this too. I tried a demo account that allowed making buy and sell trades in the same chart and made 1,000 USD in demo money. Then I got a live account with forex.com and find out that FIFO trades and only buy or sell trades can be made at one time on the same chart, not both. That messed up my strategy. First In First Out (FIFO) trade closure messed me up because you can only close trades in the order that they were made. These made my trading much harder. The US has to follow these rules so brokerages working in the US have to enforce those rules or get messed by regulators.
