Money management strategies

Hi friend, Iam new in forex(Two month only). Iam trading with price action. I know leverage is a sword, can be hit you or your broker. Money management is a technique for maximizing ur profit with reducing loss. Well i know we should use our 1% or 2% account money(depend on your leverage) to open a position. Stop loss and target is depend on your win ratio. Suppose Your lose 2 trade and win only one then if your stop loss is 30 pipes than target will be 90 pipes or more.
Now take a look here -
If your account is increasing with 20% per month and suppose you start with $10000.
After 5 month it reaches 20000.
Then (after five month) 40000.
When year complete $56000.

Can you suggest and share more good strategies of money management ?

Wrong math

10.000 x 20% = 12.000
12.000 x 20% = 14.400

after 5 months = 24883.2
A simplified formula
Es = Is (1+i)^p

Es = End sum or final sum
Is = initial sum
i = interest rate (your case 20%)
^ = power 2^4 = 2x2x2x2
p = period

your case:
Es = 10.000 (1 +20/100 )^5
= 10.000 (1.20)^5
= 10.000 x 2.48832
= 24.8832

This is why money management is so important, compounding power.

Money management is corelated with your trading system, can't have a good sytem without a proper mm

Thoughts of %300 to %500 a year are a bane to the new trader.
The trick is to make your acct last long enough to learn to trade.
Once you have done that then you can begin to think of growing your acct.
