Withdrawing money, new to Forex

I am a new trader learning about Forex and leverage ratios. My question is regarding the process of withdrawing money from an account.

I wonder if this is my misconception:

If I deposit $100 with a trade broker that leverages 100:1, that will amount to $100,000 of tradable capital for me.

Let's say I double my money and have $200,000. If I want to withdraw half of my earnings, logically (to me), the money will be then be divided by the 100:1 ratio.

Does that mean I make $100, or is it more complicated than this?

Thanks

You can trade $10k with a leverage of 100:1 if you deposited $100. And that you can trade $10k doesn't mean that you own $10k. And if you double your account you won't have $20k but only $200 which you can (of course) withdraw.

leverage 1:100 = 1% margin requirement

it means, to buy 10,000 GBP (0.1 lot), you dont need 15,900$ but just 159$ (1%)

0.1 lot gives you 1$ per pip move where USD is the quote currency (given 1 lot = 100K, some brokers say their lot = 10K, in that case 1 lot gives 1$/pip)

if GBPUSD moves 10 pip, you gain 10$, if it moves 10 pip against you you lose 10$

your broker may say, he will close out all positions if your margin gets below say 50% of your used margin

for example, you start with 500$, you buy 10,000 GBP, you used 159$ from your margin, you have now 341$ margin left (for other positions), if your account goes below 79.5$ (50%) you get a margin call, you can endure 420 pip against your position

but say you closed your position with 100 pips profit, you then have 600$

an example of extreme overleveraging (the former was also overleveraging)

leverage 1:500 = 0.2% margin requirement

100$ deposit

buy 20,000 GBP (2$/pip)

used margin -> 0.2% x 31,800$ = 63.6$

margin call at account below 31.8$ or after 68$ loss or after 34 pip

how to do it right

account 10,000$

risk 1% of account

trade plan gives signal to buy and the former higher low gives a SL of 75 pip

1% = 100$

100/75 = 1.33$/pip

open position buy 13,333 GBPUSD or 0.13 lot

margin requirement depending on leverage

1:1 => 21,199$ cant do
1:20 => 1,059$
1:100 => 212$
