I've experience same thing as well ,I stop trading because it feels like its been tampered with or manipulated somehow ,I suspect my trading platform though ,I prefer to keep investing for now
Manipulation is rampant but if ever you learn how these manipulators work and ride with them, I bet you will find it entertaining and profitable. We rarely see a market where manipulation is present. So it is best to learn the pattern that tells manipulation and take advantage of it.
