Reading the link, I saw that they said to even open a short sale << the wait tag says it all "keep on staying short or at cash" >> !!! UNBELIEVABLE !!!
First you cannot (or with extreme difficulty) short securities under $5 (it's just prevented from most / all brookers), not to speak under 1$.
Second, would it be possible, that's mere madness, to give that kind of advice with other's people money. Come on, if you were short how can you sustain a 50% move against you in a single day without having put a buy to cover stop long before these 50% have run against you. And now, are you going to wait until you loose 150%, 200%, 1000% before covering !!!!
The only good order on that kind of securities is a buy stop, as described in Weinstein. Let's say the base is @ 0.3, then you can place a buy stop @ 0,37 or 0.35$ which is trigerred if the security goes past this mark (which would have happenned on the 15th and then your stop would have probably been hit on the 68% retracement which followed on 19th, 20th, 21st with a fishing spike on 21st)). you would already be at a loss !
Then again, all that is PVBK trading and has nothing to do with investing. You do not care a damn of the company business and they could manufacture pampers for martians that would do fine if the PVBK makes it.
Now, one wishing to play the game could enter LONG with a limit order @ 0.36 (68% retracement of the last move) and place a sell stop @ 0.29 (more than 20% !!! loss). Then on the 21st CAMH lost 20% during the day on a very low volume of 48k$ (which means biggest position is a 10th to get liquidity on stop execution, i.e. 4k$ ....)
I will not do it as ROC MM200 is < 0 and the first trading rule to success is to stick with the rules. Even if CAMH makes a big run (and ROC 200 might become > 0 but too late), I will not regret to stick with the rules as statistically you only make money doing so.
If some play and win I'll be happy for them, it does not take anything from me, this is what is great with trading.
