Am not sure I understand your question but in trading some say you could trade for probability or profitability. Probability would mean maximising the number of winning trades while profitability would mean maximising the profits of the few winning trades you get. With binary options trading you need to have as many winning trades as possible because the maximum you can ever get from any winning trade is not more than 80% of what you invest yet you stand to lose at least 85% (100% is not uncommon).
But with spot forex for example a trailing stop could increase your upside in a trade a lot meaning you could earn much
more than what you stand to lose. In other words even if you make only 10% of your investment, this would not be a bad trade if your stop loss was set at say 2% of your investment.
So with Binary options you need to ensure that your trading system or signal generator is accurate most of the time and in my experience this is very difficult to achieve.
The idea is only seemingly simple. The missing piece in trading binary with your EA signals is ... Time! Given enough room for your stops and time, the spot markets will eventually turnaround. Hence, any so-so EA could still yield a fairly high probability of winnings. The same can not hold true by using just any EAs without a precise calculation on the time limitation trading the binaries!
The whole thing is a scam under the veil of "online trading". I don't care how accurate your EA is, if the system has been rigged you can't make money out of it.
