Many traders and investors use moving average lines in their trading, mostly with the well-known or common moving average periods such as 5 SMA, 8 EMA, 9 EMA, 10 SMA, 20 SMA, 21 EMA, 50 SMA, 200 SMA etc.
In the following chart, we can see Advanced Micro Devices (AMD) interacts with its ‘once support became resistance’ moving average lines (body and wick) like a chapter from a playbook:
Classic.
Note, however, that the simple moving average resistance lines are the 343 period (body) and the 355 period (wick).
– “Wait, what?! Not 21 EMA? 8 EMA?? 5 SMA???”
Nope. The ‘one size fits all’ approach does not work anymore.
The 343 and 355 periods work only for AMD, only on a 5 minute chart, and only now.
Other stocks would have other MA lines. Change the sample interval and the lines will change to fit that interval.
