I like it too.
I’ve searched for trademark issues in UK, all good. International trademark wants me to register just to check, unless someone in the field knows.
MarginX.io is nice. Dot com is taken by the broker, could be still available it says.
Marginx Web search shows a few results but I don’t think they are active anymore, needs a deep checking, if the team like this name.
PS. I checked company house. Gov so far.
MarginX.io is good
TonFx, TonFahX, xTon, FxTon, y sus derivados! Larga Vida a PundiX y FunctionX. Welcome to #Chile
FULCRUM = meaning: the support about which a lever turns the camera moves on a fixed fulcrum, either horizontally (panning) or vertically (tilting). For example:
Although marginx is a good name, but we have to decide if it fits the overall fx Variable core definition & overall functions.
This is because Margin Trading for example: You have $20,000 worth of securities bought using $10,000 borrowed and $10,000 in cash . When the value of these securities rises by 25% to $25,000, and the amount you borrowed from your broker stays at $10,000, your equity becomes $15,000.
Let’s continue our thoughts and suggestions I say, giving the team full exhaustive options.
Need more key words to play around with.
Perpetual stocks with crypto is the unique feature, and with decentralized wallet trading 24/7/365
I’ve scrolled up to see if it was mentioned already.
Stockfi.com available and hasn’t been mentioned yet. Cost 8k though 
Stockfi.io is taken by the broker could be available still. I don’t see any companies on search either.
There is no company name in company house
So I am using this link as well to check EU.

Also how about stockfinity.com available for 4k, but close to an existing forex trading site. Which is stockinfinity. Com
Tried infiniteX.com, available but cost 735k!
Infinityfx.Com is taken need brokers to possibly get it. Same with io
Fxinfinity. Com & io available
What about:
PundiDEX
Multi FX Swap
Multi X Swap
Name: EquiDEX
Short for Equities Decentralized Exchange
Website: equidex.io
Pros:
Cons:
Also, EquiX.ai is available which is shorter but .ai is not as popular. EquitiesX.net, EquitiesX.io, EquityDex.net and EquityDex.io are available as well.
Perpequity.net, perpequity.io and perpequities.com (Combination of the word perpetuals and equities) also seem to be available.
Just my thoughts:
If MarginX or EquiDEX has issues registering, why not register them as MarginX.io or EquiDEX.io (Just like Cex.io did). IO is a computer term. We can also go for MarginX Protocol or EquiDEX Protocol and in short call them their names respectively.
Trying to find a nice name with F and X in it. (maybe with or without a unlinking meaning)
For example:
FeniX (like this one)
GraFX
SuFfiX
FluX
preFX
FleX
I like marginx.io. I also like Fulcrum.
What about:
marginx.io is probably most catchy tho
I like Fulcrum
That’s a few people that liked margin X. I tried it on a tweet hashtag, felt good. Sounds professional as well.
Make a poll to choose out marginx.io & Fulcrum 
Hey Dutch, funny I was going to post one, but it already appears marginx is the best name so far. My only concern was, as mentioned above, if the name is suitable for the overall services, and if the team likes it.
Judging by this mornings responses it seems we do have a winner, and it’s pretty clear of clashes on Google searches. I really like it, actually his already the winner of my giveaway as promised, and deservedly imo. I’ll post on twitter now to be clear to everyone that have applied.
They are both good names. Both sound good when it’s said which is also important.
P.s. My tier S name is marginx
