I understand what he critizies concerning the answers: people who answer here are often too much like philosophes and psychiatrics.
There was a simple question.:
How manny lot can i trade with 200000 Bucks and how many lots can i trade in general with a broker?
The question was not what someone should do before he deposits money and trades.
I asked the same question my online support cause i plan to trade 10 Lot /trade, the margin for EUR/USD is approx.2000 EUR.
In general “normal” Forex broker let you trade max 50 Lot a positions. If i had more monney to trade i would try to get in physical contact with a broker and enter his office to talk about circumstances, like in the good old times.
So in most cases with online “brokers” you can trade 50 Lot positions maximum.
