The minimum deposit to follow my signal is 500 units. For example, wlen I've started this, I began with 500 US cents, seen as 500 USD on an InstaForex Cent account. InstaForex has a non-standard unique way to work with lots, so I had to multiply a 'normal' lot with 10. What I want to say is that, starting with 500 units, first ever trade should have lot = 0.01 when expert advisor starts. If somebody copies the signal, eventualy, feed it back in terms of lots, start time and account balance (or lots/balance ratio if you want to keep your balance private), I'll analyze if it's well balanced. My account has a leverage of 1:500 but the expert advisor has a built-in VirtualLeverage function that limits the leverage at 1:100. It's better if your account is 1:100 from the start.
Indeed, one or more trades went wrong could end the account. It happened before in more than 2 times, it will happen again. Swap also can eat up the profits. For example, the trade started in September 2013 has already gone unprofitable. I will correct this in the future but it's not that important to me.
As I specified in MetaQuotes Signals, I don't recommend anybody to follow my signal. If you do, you're on you own :).
Thank you all for the interest,
