I explain with an example, this system sold in ogosto of 2018 CRUDE at a price of $ 68, and closed the operation in December at a price of $ 45. But it turns out that before going down to $ 45 it went up to $ 76. With a small account you can’t take this without the broker closing you due to lack of margin. That is why in this case I recommend financial options far away in time. If you do not know what are options you should read about that, they are not binary options, they are financial options, it is important not to confuse them, because for me binary options are a scam. The advantage of the financial options is that when you buy this option, you will have the position open until its expiration, regardless of what the quote does to date without any problem of margin in the broker’s account.
