"They all show only what might happen based on what has happened in the past."
Absolutely correct, es1. If we knew what was going to happen to a stock in any reasonable time interval of the future, then we would all be millionaires by now. It is pretty unsafe to try to tell what is going to happen tomorrow from a bunch of ... candles (e.g.) of yesterday.
Charts only describe what happened in the past. Charts of
the future cannot take into consideration all those
incomputable variables in the stock game, and, especially,
in the penny stock game. There are: human behavioral
tendencies (emotional outbursts, fear, enthusiasm, etc),
panic selling/buying, buyout possibilities/offers, market
makers' manipulation (short covering, etc.), company
information/misinformation, false/correct PRs, lack of PRs,
too many PRs, fluff PRs, false/correct financials, audited/unaudited financials,
pumping and dumping and bashing, dilution, etc., etc. We cannot handle
that many absolutely complicated variables in any possible
applicable modeling/statistical adventure. We might be able
to predict where a hurricane is going to hit land
three days from now, but not the future behavior of a penny stock.
