This hourly chart presents an indicator that could work as a green-light/red-light signal for the management of a trading position for TSLA. So long as the 50 is above the 200 it's all systems go. Should the 50 drop below the 200, lighten up or exit waiting for either (1) the next short-term signal, or (2) the 50 crossing back over the 200. We will have to watch it going forward for real time effectiveness as it carries more logical weight than an arbitrary trailing stop.
