high gains comes with higher risk.
its how 1 manage it. every1 is unique and has diferent risk level and appetite.
500% is a meaningless figure unless you can state what the initial deposit amounts are, time period it is over, if it time-weighted return Gain or Absolute Gain, or CAGR.
its all about risk, my general rule of thumb for benchmark any fx trading system or investment is about 5:1, return:drawdown, which i think is a relistic return profile for the markets. its easy to make 250% or 500%, however you would have to have 50% or 100% of your capital at risk. Margin calls with most brokers normally happen at 50-70% depending on the instrument.
I normally accept a drawdown of around 10-20%, so im looking for return profiles of around 50-100% per annum.
but realistically speaking, even if your risk appetite is high, the maximum returns you expect in fx trading without risking too much and most certainly blowing your account is around 250% per annum.
With experience in many forms of fx trading be it, price action trading, technical, fundamental, or algorithmic, as well as having managed accounts with numerous reputable traders, i can tell you it wont get much better than this without over leveraging and risking too much on your accounts.
even if you can achieve 500% in trading... the markets are constantly evolving and changing. its near certain, whatever might be working for you in the short term, will not work for you in the long term.
best advice, is to make sure you dont have all your eggs in one basket, and diversify your portfolios as much as possible, and have as many non correlated "edges" in your arsenal as possible working together collaboratively.
