Forex strategies loses efficacy as you increase the budget. This is why great forex traders don't necessarily make great hedge fund managers, or move from one position to another.
Liquidity is not infinite as you think. It may be infinite but not instantly and not all in the same broker. If you want to make a 200 hundred thousand dollar trade, that's institutional trading, and your own trade will change the price a bit so it will stop making sense as the price moves.. Or your broker won't have the needed liquidity to cover it (Or don't want to risk it).
This is why banks trade different than small traders. You have to do your orders in small parts and this changes the game totally. You are now a liquidity hunter looking where you could get the needed orders to fulfill yours.
While as a day trader you don't care about finding liquidity because your broker will provide it instantly, so you are just riding institutional movements.
I know very good traders, and the cap is more or less around 50k-100k per month, as a day trader. But the ability needed is something really hard to achieve, I couldn't.
That being said , this post is scammy as fuck. Show us some of your skill instead of just talking about your profits and expecting people to send you dms, OP.
