let's set some ground rules:
-try not to repeat points.
-TA is a hypothesis that needs to be discredited properly (rigorously), i.e. not in the manner that nanopene employed.
-'disproving' TA involves proving a negative, which is not possible. avoid the use of that word altogether and stick to the idea of evidence.
let me also open with a well-defined hypothesis:
"
Since there exist time-dependent autocorrelations in price data, past performance sometimes correlates with future results."
evidence against TA would be evidence that time-dependent autocorrelations
do not exist in price data.
'disproving' TA involves providing an example of a prediction made by TA that turned out to be false. It happens all the time on this forum. I do not have the time to do it now, but it would be pretty easy to take a bunch of charts from the past, ask the TA people to predict what will happen next, then reveal the next week of the chart and check their answers.
