Last year I used a $15k account (real trades) to see how long until I could double it. I was doing some overnight and weekly trades. Overnight just too risky and is where I had most losses. Weeklies worked well. I hit a double in August. October I started doing more monthlies when market got crazy with Ebola issues. Here are the trade details: https://www.dropbox.com/s/3h3vz6rtbh40mys/Double Money.pdf?dl=0 This year I'm doing a Double attempt again but just using weekly SPX spreads. 12 trades so far and 18.09% return. And that includes a loss the first week as it hit my $1 loss / exit rule. So for me, this works well for a portion of my capital. I keep it to less than 15% of capital due to the catastrophic risk.
