Spoof Trading and Downticking Spoof Trading and Downticking are 2 other ways to influence the stock price negatively as described in:
https://www.equedia.com/canada-stock-market-manipulation-transparency-issues/
Spoof trading is when a trader enters deceptive orders tricking the rest of the market into thinking there's more demand to buy or sell than there actually is.
Downticking is when a trader sells stock so that the most recent change in the share price is negative. This is usually done right before the market closes using very small amounts.
And since stock charts only follow the closing price of a stock, you can see how easy it is for a short seller to create a nasty looking downward chart by spoofing and down-ticking.
These practices are illegal but happen to many Canadian stocks.
The next time you see a stock in the green for the whole day, only to end up in the red with less than a minute to go, you now know what could have happened.
I have seen several occasions of downticking ALP in the past.
It is obvious to me that there is evidence of tampering with the share price negatively for ulterior motives, not known to me or the general public.
