This is flawed logic. Swing around 20 lots on $4K? That's just $500 margin per lot! But even assuming that someone had access to that insane leverage (I certainly don't come close at I.B. nor do I feel the need for it), you need to also account for the maximum drawdown, which is another $4500. Otherwise, commission on entering a 20-lot trade alone would trigger a margin call. :eek:
So at the very least, the $150K combine would be somewhat equivalent to a $8500 account at a hypothetical broker offering $500/lot margin. Now, at a broker with more sane margin, say $1500-2500 depending on the contract, you're looking at more like $35K to $55K equivalency.
So while I agree that the "$150K" is purely for show, especially knowing that their true risk is around $4500 plus overhead, it's not nearly as inflated as you calculated. More like 3-5x, not 37x. It also has its use in my risk management: by risking 0.6%/trade on a hypothetical $150K I always end up with anywhere between 4 and 12-15 lots on my trades, so their 20-lot maximum sounds roomy enough. At least for me...
Lots of brokerages offer $500 margin. That aside, understand the "$150k combine" isn't real money. It's a practice account. They're not extending you anything!
Once you get "funded," they start you out with an account that, by your reckoning is equivalent to, $3k-to-$4.5k max.
I guess if you're a homeless person who's a master trader that could be an attractive proposition. Beyond that, I don't get it, either.
But for stocks, which was the reason I opened it originally, they're by far my favorite in Canada, especially now that they have RRSP/TFSA accounts which might come in handy soon. For futures, when I looked into them a few years ago, none of the decent brokers allowed accounts from where I am (QC, Canada) so that was that. No longer interested in CFD bucket shops.
