i know there is one binary option broekr where to add external wallet, so u don't risk your funds. is there some other brokers (fx or binary) with the same safety?
Even if a broker offered a fully external wallet, they would require full instant access to it. Let's see what they'd do in a typical forex trade.
You try to buy 1 lot of EurUsd. The spread is 1.8, so first the broker has to make sure you have enough money in the wallet and then deducts the $18 dollars of spread.
Price moves down 1/10 pip. Broker takes $1 out of your wallet.
Price moves up 2 pips. Broker puts $2 into your wallet.
So, EVERY price move requires them to directly access your external wallet. If you keep a trade open for a few outs during an active market, you wallet gets hundreds of small transactions. Do you think SaveExteralTradingWallets, Ltd is so nice that they want this to happen on all your trades and all the trades of all other customers without charging some sort of fee?
Also back to step 1 of the procedure - the broker has to check your balance. This it time that will be added before your trade executes. That could easily result in slippage or requotes on your order.
I know someone reading this will say "But the broker could just resolve the difference after the trade closes." Yes, the broker could do that, but would lose vast sums of money? How? Easy.
I and a friend open external wallets and broker accounts. We wait for a day with several big news events. Before news event 1, we open big trades opposite each other. If the news event is boring, price moves little. We close those trades and get ready for the next event. It's BIG. My account is heavily damaged, but the broker hasn't removed my losses yet. I withdraw my cash from the account and just leave the trade hanging there. My friend made a bunch of money. He closes his trade, the broker sends the cash, he withdraws it.
Even without an evil plan like this, someone who has a big trade go hard against them could just pull all of their cash out of the external wallet before the broker pulls the lost money out.
This means that anything short of the broker moving money in and out of the account as price changes puts the broker at risk of clients running off with cash owed to the broker. No sane broker would do this. Some brokers might lie about having all client funds being somehow out of the broker's control. If the broker has no access to client funds, then neither client losses or gains can be dealt with.
Some brokers do offer "segregated accounts." That just means that client money is kept in a bank account (100% under the broker's control) that's clearly set up to ONLY be client funds, not for broker operational funds. Every so often (determined by the broker and/or its regulators) net changes in client equity are moved into or out of that account to keep it very close to equal to current client equity. None of this means the broker can't steal the money. The broker could always just decide that all clients lost all their money. It does mean that if the broker goes out of business, non-clients owed debts by the broker can't file claims against any client money in the segregated account.
