If i start trading a combine, e.g., 150k, and immediately I incur a loss and my account balance drops below 150k, I assume I have to restart again, right? Also, if i pay the fee to participate, e.g., $375 for 150k, and I have to restart, what about the $375 I payed, do I have to pay again?
If you start a 150K combine, you can go down to 145500. Losing a maximum of 3K each day/week until you reach the maximum drawdown. (Weekly only in stage 2)
If you make a small profit of lets say 2K and then start to go down then your trailing drawdown is 2K higher, so at 147500.
If you reach 4,5K profit or more the trailing draw down will stay at 150k
If you do a restart then the combine keeps going, so you have to pay the 375$ again for the next month, the 375$ is a monthly fee until you complete stage 2. So a restart only is interesting if you are more then 5 days away from the payment renewal and you believe you can make the target in the remaining days. If you think you will need lets say 10 days and there are 5 days remaining, it is better to just stop the combine and start a new one.
Remember you now also have to pay for stage 2 since the rules changed some time ago.
