On Monday, I invested 40u to trade event contracts. After losing both trades, I invested another 40u and made it to 500u yesterday. Today, I took 30u to try rolling over; if I win four consecutive trades, I could earn around 280u. However, if I encounter a loss, I will lose 30u and pause trading. I have won three times in a row now, and the last trade was very lucky, coming in the last two minutes. I'm struggling with whether to roll into a fourth trade; if I do, I must find an excellent opportunity. Alternatively, I could use the 30u to roll as well.

Using the rolling method to trade event contracts is actually feasible. With a multiplier of 1.8 to the fourth power, it becomes 10.5. Winning four consecutive trades could yield a 9.5 times return. If I continue to roll with the same capital, every nine losses, if I achieve one four-game winning streak, I can break even. If the win rate is high enough and the opening frequency isn't too high, the rolling losses are controllable, and the returns are quite significant; the speed of capital growth is impressive. Of course, the premise is a sufficiently high win rate, like 75% or 80% in daily trades. Below that, I wouldn't recommend it. If losses of five or six consecutive trades happen often, then no matter how you manage your positions, it will be futile.

Finally, I want to say that any fancy position management is just supplementary; everything about event contracts hinges on the win rate.
