Hey Ilan,
Glad to hear from you, and that you figured it out. Sorry for the late replay, I just don’t succeed sometimes answering everyone everywhere – forum, Facebook, youtube… but I did it to myself :)
Regarding the broker, it is really up to you. I avoid recommending it. Even the brokers on the website, I do not recommend them, I asked my team to place regulated brokers so it is easy for the beginners. Coinbase does not offer MetaTrader. Just exchange.
Above the swap, you have Swap Type – in percentage in your case. I think it is a percent of the position size.
Regarding the formula. let me know if there comes something new that is not clear.
