That is the reality in regards to TA. It is to believe that those passive traders don't rely upon TA's but having in the actual scenario and adapt to it will it exactly could help them. Traders should become vulnerable to that kind of change and we can't expect that TA's will work great all the time as we know how volatile we are.

Whales probably don't have that kind of analysis, instead, they go along with the market and use their manipulating power to change the trend. Besides, most traders are relying on their actions and predicting what they'll do next rather than to keep TA's.
