I have an account at AMP, where CQG feed is $3/mo (CME L1). No maintenance fees. Want to open an account at another broker with CQG feed (also CME L1) at similarly low cost, if possible. Edge Clear is $2/mo + $10/mo API fee (seems the API fee is not optional); no maintenance fee. Anything cheaper than that? Willing to pay slightly more in margin; just want low monthly cost b/c this account won't be traded much. Rithmic would be ok as well, but as I understand it, there is no escaping higher monthly fees with Rithmic.
Why are you looking to open multiple accounts at multiple brokers? What kind of deposit are we talking about?
Have a look here for possibilities... https://www.cqg.com/partners/fcms?f[0]=exchange_connections:CME FWIW, I understand the multiple broker diversification (would be better if it's fcm diversification, but ok). What I don't understand is why the same feed? A backup data feed is useful to have.
If you won't be trading that much as you say, what's the point of opening a second account? I also noticed you already have access to TOS, so why not use that as backup (if that's what you're looking for)?
The account would be for a family member. I want to be able to copy trade, so TOS is out. Can't simply open the account at AMP, which would be my preference, because AMP has no LTAs (limited trading authorizations).
If it's a family member just trade for them. Make your own LTA, who cares. Get AMP, sign up with MT5, then use trade copier to replicate.
I'm guessing AMP will see that the trades are identical and have a problem with that. I could certainly write up a LTA that my family member would sign, but AMP isn't going to accept that. Though if I can't find a good alternative, I might do as you suggest and ask for forgiveness if it becomes an issue for AMP.
