I dont think it matters, but read the signal start FAQ. It works out the % of my account that I'm risking and applies the same % to yours. so you could start with any amount.
BTW I will be putting my prices up each month, those who subscribe now get to keep the same rate.
Be advised that this is a higher risk signal for the purposes of trying win the contest ( and I will continue to trade it the same way thereafter), so this is a service for those with an appetite for higher risk/reward.
My lower risk signal begins next month and I will be running both in parallel.
