I added a bit to my robot positions in IWM and TNA; still waiting for UWM ...

Position size is small.

Formula that I use which risk-adjusts based on ATR is:

[ Account value * Pos'n Size ] / [ ATR(20) * Share Price ]

So as volatility goes up, the amount you buy is dropping.

Entry points are below the following:

IWM:<73.17
UWM: <33.75
TNA: <45.20
