1.The market Is not control by bot but traders who are humans who place orders.
2.Emotional sentiment by traders can drive the direction of the price which the bot might not detect.
3. Crypto news channel also drives the fluctuation the price such as the sudden announcement of ban of crypto asset by China or any other countries.
thanks for your comment . i want let you know that market direction is not only by TA analysis . there are factors that drive price to any given direction . bot are good but is not what you should depend on making critical decision on financial instrument trading . the banks and other financial institutes dont use Bot to trade financial instrument . secondly i will create your indulgence that you dont need to limit your trading knowledge only to crypto currency exchanges but also to other plafform such as forex platform where bitcoin , ethereum , ripple are listed as crypto asset instrument . these are the big institution that drives the price . if you follow up NASDAQ news recently you will discover that BTC and LTC have been listed among other stock . i hope l made some point to you .
