Here is an updated CEN chart along with 5 fairly active indicators that I consider suitable for monitoring the current uptrend. While CEN is currently looking good, this is no time to blindly "buy and hold" ANY stock.

Note how price action accelerated away from trendline (1) rendering it obsolete. Ditto trendline (2). Trendline (3), although confirmed, now looks to be too steep to sustain. In the absence of other signals, any break below this trendline should probably be ignored unless you really want out.

The RSI(24) oscillator has today become technically "OverBought", and will trigger a "Sell" signal when it drops below the OverBought threshold. Unless this signal is confirmed by some other indicator(s) it should be ignored. This oscillator can be "detuned" to some extent by using a break of its trendline as the trigger, rather than a break below the overbought threshold. With uptrending stocks, it is quite common for oscillators like the RSI to remain around overbought levels for long periods of time and to give a string of "Sell" signals. Any RSI "Buy" signals will mark good entry points, though. You can see here that the RSI signalled a "Buy" over a month ahead of most other indicators featured here. Even the OBV trendline break confirmation didn't come till more than a week later.
