Hey Jankrafka,
Yes, this dosn’t sound right. I never heard of that.
First, a legit broker should not give advice.
Second, they should not place such conditions.
And third, you should be free to open any type of positions – with SL and TP, without, mixed, anything that you like. And most importantly you should be able to withdraw at any moment you decide.
Please, have a look at the trusted Forex brokers we have on the website and get rid of the scammers.
Cheers.
