$DRWI, buying off of solid support (of multiple time frames) is rewarding

$DRWI basically a tech stock was trading around just under 70 cent when this new came out

Look at screenshot , arrow 1

After market it spikes but consolidates around 1 dollar level (so that's the resistance), arrow 2

Early Premarket (7:30ish AM) I spotted it on scanner as it went upto 1.10 (arrow 3), I didnt buy it as I didnt want to chase it.

It then came down to 1 dollar level that was the previous night resistance and held it as support.

So a solid entry there. I bought it and sold it at 1.07$. but I went upto 1.22 (arrow 4), sold too soon as I had multiple positions.

Anyway the real predictable trade was yesterday. All day it held support around 1 dollar again. 

After market and Premarket it spiked upto 1.4 to 1.5 isch. So a buy at solid 1 dollar level support could have yielded around 40% gain selling after and pre-market. 

As yesterday today again at market open it failed to hold its gains.
