What you do is you adjust the Margin slider until you get a capital required that you are comfortable with. Remember that Capital Required is the total largest drawdown in the past including open interest and margin. This is the amount that you should expect to drawdown again as some point, and statistically to eventually drawdown more.

Generally speaking, traders tend to set a maximum amount they are willing to lose before they stop trading. You should set the Margin slider so that this is the Capital Required. To put it into an orthodox perspective, a common drawdown a trader is willing to risk is 20% of their account. At this point they will stop and reassess. Suppose the flashy yearly return in Zorro is 200%. Then the actual return on the entire account is 40%. For example, suppose you will risk 20% of your $100 account and you will make 200% of what you risk, which is 200% of $20 = $40. Then you actual return is 40%, that is $40, not $200.

Of course, if you want to risk 100% of $20, or 100% of $100, for example, go for it. Of course, the real numbers are in the low thousands as a minimum.

Just think about this and consider what your risk tolerance is.

This topic was discussed at length sometime in the last 12 months. Generally there was a few of us that were frustrated because out accounts were going down when the Zs equity profile charts were going up. There is no proof or transparency of real results, just hearsay.

If you have not already purchased zorro, I suggest you just subscribe to the systems you want to try. You can buy it out of your profits at a later date. Paying $500 up front is a huge risk. If on the other hand you are a programmer and a trader already and you want to mechanise a system you know works then go ahead and buy the full version.

If you are not a successful trader already, then I suggest you walk away. This is a great piece of software, but it is not for beginners, not for passive investors and not for discretionary traders.
