Signals and Trades
Not all signals are acted upon and signals are often reinforced in this type of strategy. If you are long in the security, buy signals are not acted on, for example. Similarly if you are short you must ignore sell signals. There were 162 buy signals and 43 sell signals for this particular AAPL strategy .These led to 23 round trip long trades of which 14 were profitable, and 24 short trades of which 18 were profitable. This is a daily strategy; daily OHLC data is used to derive all signals and there is at most one buy and sell signal and one trade per day.
Drawdown and Reward/Risk
Drawdown (the worst case loss for an single entry and exit into the strategy) was 9% for long-short and 11% for long only. This compares to 14% for buy-hold. The reward/risk for the trading long and short was 6.09 vs. 2.33 for buy-hold, an improvement factor of around 2.6 If traded long only, the reward/risk was 4.14. We use drawdown plus 5% as our risk metric, and annualized return as the reward metric.
The backtests assume a commission per trade of $7.
