What does The minimum turnover requirement constitutes 2.5 million USD for every 100 USD won in the contest mean can some one explain it to me
That's mean, if you have 100 USD, you have to made a several position that will use a 2.5 million of volume in sum. For example if you open 1 position for 100 usd and use of leverage 1:100 that's mean that your position volume is 100 usd*100 = 10 000 usd, or 0.01 million. 250 such positions is 2.5 millions. But also don't forget about a commission and loss positions etc. This system works good if you do a good trading, and multiply your equity.
