Andy, I wanted to elaborate a bit on the system that you are looking at. As you probably know, moving average systems such as this are trend following. When you catch a trend, the profits just keep rolling in. These can be viable systems, but it's good to understand them before you put you money on the line. --------(For anyone reading this posting: I neither endorse nor disclaim the following system, all results are based on simulated backtesting of actual contract data. Everything below is stated for informational and demonstration purposes only.)--------- So as an example, I've written a system to backtest in Metastock on the NQ (NASDAQ Mini's). I think you mentioned 1 minute charts, but I don't remember for certain. For this example, I'll use it anyway. I've chosen a 5 minute simple moving average compared with a 30 minute simple moving average. No overnight positions and I'm trading it only between 10 am and 4pm. All positions are entered at the open of the bar following the signal. The only stops I'm using are at the end of the trading day. All other exits are based on a reversal of the moving averages, so you remain in the market all day, either long or short. For an out of sample backtest, I'll use the NAZ Mini, Dec00 contract (NQ00Z in QCharts). From Sept to Dec, the system generated 248 trades (103 winners and 145 losers). Winning long trades were 51 of 124 total long trades and winning short trades were 52 of 124 total short trades. The net Points profit for those three months was 808 points with no allowance for slippage or commission. So, if you were trading 1 contract of the NQ, you would have generated (808*20)=$16,160 in profit per contract. Sounds great so far, $16,160 in profit and you put up only $11K or so in margin. Nice return in three months. I ran the same test on an out of sample set of data: the most recent NQ for Dec to March (NQ01H in QCharts), these results were similar, with about half the profits per contract at 431 points. Using the same analysis of the t-statistic that I posted a while back, it shows slightly better than an 81% probability of continuing to perform in the future. Now for the bad stuff, and this is where someone really has to understand a system in order to trade it. The maximum open trade drawdown was 31.5 points (over $600 per contract). The maximum open system drawdown was 57 points ($1140 per contract) which means that at some point during your trading, your net account balance was negative by $1140 per contract traded. The low win to loss ratio produces another trader psychology question: the greatest consectuive wins is 4 and the greatest consecutive losses was 6. Can you trade this through 6 losses in a row and still take the next trade? Oftentimes, in trend following systems that next trade could be the biggie that makes 3 times what you've just lost. I'd start to worry that this system is broken if I were to get 10 losses in a row, although there's a lot written that says this could happen statistically. These are personal decisions that have to be considered by each trader contemplating this sort of a system--before any money gets traded in the system. Also consider that I've set up the backtest with the assumption that a trader would enter on the open of the following bar. That's pretty quick, considering you got the signal just one second ago. Consider some slippage and staring at your computer screen pretty intently when the moving averages start to come together. For comparisons sake, if you were to enter on the CLOSE of the following bar, the net system profit is just 401 points in sample, approximately half of your profits are made in the first minute after the crossover. (That in itself may be worth looking at in another system...a very fast system). So, Andy, those are some hard questions for your consideration. It also gives you an idea of just some of the things you can do with some of this software.
