Trading long is better business model April. Even in a downtrend. It's way easier to build techniques around long only. Shorting requires far more precision and are harder to build, it's more a specialist activity. But don't take my word for it, test it yourself.

Shorts have their place just mean revert springs/price spikes and make them snappy is my 2c.

Calvo has been screaming this at the top of his lungs for 18 months to help those with short bias. It's from experience and he's right. My life has been much easier since I saw this in back testing.
