this is some seriously muddled thinking ... first you are claiming that the market is totally rigged (I somewhat agree with you) and then you claim that some kind of TA will be effective in predicting future prices.
If the market is rigged TA is useless, except perhaps for the market riggers, who can paint whatever pretty picture they want with the price moves, including dragging TA-'sensitive' bots up, down and sideways, like bulls being led by a nose-ring ... in which case it is more rigged than you imagine.
If you are a whale wanting to manipulate a market up, or down, it is essential that you get the little fishes to take part, otherwise, you don't make no money. You get the little fishes to participate by providing them with convincing bullish or bearish technical set ups. TA does work, to the extent that it represents market sentiment expressed in a mathematical and/or graphical form. It also works in terms of how many traders subscribe to it's essential guidelines. It doesn't work in the sense that a whale can turn even the most bullish of set up's on their head and sent the market in the opposite direction.
But whales make money from market volatility which they induce. If you want the market to take a tumble, you can mould the market into a bearish TA set-up, which we seen in Bitcoin around the $360-$380 zone. I believe we are now seeing the formation of a bullish TA setup, again one that is being moulded into being by some very strong hands, but of course, regardless of what the TA states, the whale has the power to send market in complete opposite direction, such as we seen on Stamp, where some whale triggered a bunch of Panic Buys which he no doubt dumped into....completely unpredictable, and in complete contrast to the what the TA was stating.
