What are the guarantees that the stock broker will pay the money?
Currently, Forex trading is not possible without the participation of an intermediary, which is a brokerage company.

It is the broker who transmits your trades to the exchange and pays you the profits you receive from successful trades.
At the same time, most traders have a reasonable question: what guarantees are there that the broker will pay out the money earned?
It is clear that if we are talking about amounts of a couple of hundred dollars, then no one will ruin their reputation because of such an insignificant amount.
But if the profit amounts to several thousand or even tens of thousands of dollars, will the intermediary refuse to fulfill its obligations to the client?
Why are there practically no problems with withdrawing profits from a broker these days?
The point is that almost all modern brokerage companies are intermediaries and do not themselves act as the second party in transactions with clients.
They simply take your money and transfer it to the market, where the second participant in the transaction is a trader just like you.
If you make a profit, the other trader suffers a loss, and the broker still wins and receives a commission (spread) for bringing your trade to the market.
Therefore, there's no point in a brokerage company denying you the withdrawal of profits. The only exception would be if the broker is a back-office broker and is the other party to the transaction.
Therefore, for large-scale trading, it is advisable to choose brokers with ECN accounts - https://time-forex.com/vsebrokery/ecn-brokery
Which brokers pay exactly?
Speaking about my experience of withdrawing large sums, they were not truly impressive and were limited to a couple of tens of thousands of dollars.
Over ten years of Forex trading, I've withdrawn money from the following brokers:
InstaForex – the maximum withdrawal with this broker was $19,000, with withdrawals completed within 24 hours, and no additional checks were required.

In fact, this was the largest withdrawal in my trading history. I was nervous, but the money arrived in my account within about 20 hours. InstaForex's website is instaforex.com
Alpari – I once withdrew $9,000. Before the transfer, the company manager called to verify and clarify the reason for the withdrawal:

I submitted a withdrawal request before 9 a.m. and received the money that afternoon. Timing is also important, as many brokers only withdraw funds during business hours. Alpari's website is www.alpari.com
RoboForex – my achievements here are more modest, with the maximum withdrawal amount being $5,500:

There were no additional checks; the funds arrived on my card within literally an hour. I was especially pleased with the lack of withdrawal fees. I managed to save about $55. RoboForex website: www.roboforex.org
In more than ten years of trading, I have only encountered a withdrawal problem once, and this was due to the bankruptcy of the MMCIS group company, caused by political events.
After this, I became even more wary of companies with so many MM letters in their names and try not to keep my money with one broker.
Finally, it should also be noted that today, clients of virtually any broker are insured against its bankruptcy for amounts ranging from $20,000 to $100,000, depending on the brokerage company.
