Valuating Self Wealth & Competition Risk 2021 and beyond, page-9

Came across marketech the other day. You get your own HIN and the cash management account is also actually yours. This means I keep the interest and would be covered by the government bank guarantee. Pretty sure I'm not covered with SWF at the moment. Correct me if I am wrong. $10 per trade if trade value is less than $25K. $5 per trade if you pay a monthly fee. Am interested to hear if anyone has used them and is it actually any good.
