We call this a daily strategy as daily OHLC data is used in the numerical analysis leading to at most one buy signal and one sell signal per day. However, not all signals result in trades. If you are already long in a security, buy signals are not acted upon, similarly if you are short you should ignore sell signals. There were 259 buy signals and 290 sell signals for this particular AMZN strategy which in turn led to 128 round trip long trades of which 81 were profitable, and 128 short trades of which 64 were profitable.

Drawdown (the worst case loss for an single entry and exit into the strategy) was 13% for long-short and 8% for long only. This compares to 29% for buy-hold. The reward/risk for the trading long and short was 6.31 compared to 1.21 for buy-hold, a factor of 5.2 improvement. If traded long only, the reward/risk was 5.91.
