If you spend your life saving money you will not spend time making money, who cares about how many lose money, the only metric that matters is if you profit, unless you work for or get a commission from IB, then it does matter. Update: 1) my mistake, I just remembered you made losses with IG and will only target 1-2% per month, then the commissions do matter to you because it will materially impact non-profits, it's not the smart way to trade but it is how most trade, it is what it is. 2) no one gets any algo access the past years because it's a waste of time, even when you provide the trades the newbies (and experienced for that matter) decide to trade on their own and blow not just the profits but the capital, always ignoring the rules thinking they know better or this time it's different. 3) IB is better for those with capital, experience and stay away from margin, IG is better for burst profits, high profit targets, and diversification plus segregation of capital (usually Forex and some Futures).
Ah ok now it's clear. In that case no biggie. So the basic splitting of pounds per institution at 85k max as per FSCS (UK) and 250k for the folks in the US right principle should apply to folks. Just a reminder. I do wonder what the big shoes do though. I guess at that point one has to accept the risks...
So you choose a worse broker because you can afford it. Makes a lot of sense. I will let you continue on your succesful journey. Since you are happy with IG, stay with IG.
I am fully aware due to air pollution from global warming, poor diet from inflation, and corona from the idiocy of the human race, everyone is acting stupid with minds as dark as Vantablack, but it was clearly stated above not just by myself - IG is no better and no worse than IB, they suit different purposes. To incubate a hedge fund IB was used for Stocks (experience, capital, limited leverage), but due to timing the majority of profits were made via IG (increased leverage via CFDs), and another two brokers (standard leverage) targeting Forex and Futures. I usually don't use them personally, mainly for hedge funds and family office environments, I use brokers with 500:1 and above leverage, it's more fun and I have to work less for the same profits
IG You receive the relevant interest rate benchmark, minus 2.5%*. If the interest rate benchmark is greater than 2.5%,* we credit your account; if the interest rate benchmark is less than 2.5%,* your account is debited.
With Spread Betting indexes you don't get hit with massive Capital Gains Tax, so not sure how IB fairs after that deduction, compared to IG.
