How much money do you put with your Broker?

Okay i am under the impression that most notable traders do not put much of their money with their brokers.

Say i have 100,000k to trade with.
My risk is 3% per trade.
And my stops are variable, but is at max 100pips, min 50pips.
I have a max of 10 open positions at one time, 30% max exposure.
And my broker allows me a margin of 100:1.

With this i work out that,
My margin per contract is 1k,
i can play a min of 3 contracts per trade max of 6 contracts, depending on my stops

So my margin per trade is abt 3-6k.
I have max 10 open positions at a time which works out to be min of 30k to max of 60k. So i'll place abt 70k, instead of 100k with my broker. I wonder, if thats what all of us here do? Or
Does anyone use all their trading equity and dump it with their broker?

With an un-regulated broker, never more than $5K, always withdraw profits.

Un-regulated brokers take e-currencies, outright avoid.

With regulated brokers, with good capital, upto $100K

More than $100K, let your bank manage your portfolio.

I hope this answers your query.

Never, never more than $5K with brokers with e-currencies.

Considering that the largest e-currency, e-gold was shut down by the Secret Service and FBI this past summer, I wouldn't even touch anything dealing with e-currencies with a ten foot pole. The reason why e-gold was shut down was because the US govt finally figured out that 99.9% of e-gold's business was money laundering and Ponzi schemes (aka: HYIPs).

Brokers that are "unregulated" (I'm assuming no oversight from NFA, CFTC, etc.) are becoming fewer and fewer, and their advertised spreads are often wider than the "regulated" brokers, so I wouldn't know why anyone would want to trade with an "unregulated" broker.

As for dealing desk brokers (about all of them, except a few), I wouldn't put more than $50k-$100k, and if they offer leverage above 1:100, I wouldn't put more than $10k... actually I would avoid 1:100> as well, because the reason why they have such high leverage is they want you to go broke faster on the spread (think about it: 3 pip spread on 1:200 leverage is twice the money of a 3 pip spread on 1:100).

As for ECN or non-dealing desk brokers (I can only think of three: Interactive Brokers, Dukascopy, and EFX/MBTrading), putting millions with them is fine. The reason why is because they're heavily regulated, are used to dealing with high volumes, you get to see actual bank quotes, you can trade between the bid/ask, and two of them trade other instruments as well (ie: futures, stocks, bonds, etc.).
