GDXJ - A model for algorithmic trading relative to the junior gold miners and explorers. "GDXJ ETF, also known as the VanEck Vectors Junior Gold Miners ETF
(GDXJ) , is an exchange-traded fund that tracks the performance of small-cap companies involved in the gold mining industry. The ETF is designed to provide investors with exposure to junior gold mining companies. Typically these companies are smaller in size and are involved in the exploration, development, and production of gold."
Algo traders use the gdxj not only to trade gdxj listed companies but can and do target companies such as TUD to do their automted .
trading programed in lock step with the gdxj.
Much of what gets programmed into the automated platform is word for word translation from the FED regarding inflation.
The algos are then programmed to react automatically to whatever the FED says no matter how skewed any and all the data is on inflation, interest rate projections, data pertaining to the CPI, GDP and unemployement or where the economy is at and where its headed.
These algos are largely programmed to trigger selling mainly to whatever lying government and a lying FED put out there on a daily basis, should be outlawed along with naked short selling wherever it goes on.
As i have been saying, a couple of good NR's can break an algorithmic lock on any stock, even if its just one single solitary algo trader and leave him and or them in the dust.
