Trading the SPI

The graph compares idealized trading of the ASX200 futures contract, known as the "SPI" (share price index) vs. buy and hold. The trading uses my new day-trading approach. I actually transcribed by hand all the opening, high, low, and close values off a chart of the past month with 8 hour bars to get the data. The ticks are each of the five daily 8 hour bars. Yes, they're not all actually 8 hours long. 9:50-10:00am is one of them! Each index point is worth AUD 25 per contract and this tracks trading one contract.

The good news is that trading would have made money over the past month. On the other hand, buy and hold would have done just as well. But trading is less volatile. Hopefully, trading also does better in down markets. As I started near the end of this chart, so far I have lost money. But I have been making money in daytrading the Australian Dollar and the S&P 500 index in the last week. I also did a rough backtest on the NASDAQ 100 Index. But as I don't have access to bulk hourly data I can't do very extensive backtesting. Either I need to get that data or I need to just trade at a small scale until the results are statistically significant.
