What does that question even mean? Technical analysis is something that's used to evaluate and analyze the markets to potentially make better trades. How can something that's not even an event/incident nor an entity cause a price movement?
A lot of people believe TA is a "self fulfilling prophecy." The idea is that traders all see the same thing (like a triangle breakout or a head and shoulders pattern) and follow the chart patterns, and
that's what causes price movements.
To me, it's a really silly idea. What's pressuring price IMO is supply/demand imbalance. For example, when an upside breakout occurs, all the trapped sellers buy back, forcing price higher and higher. It's not the triangle or falling wedge pattern that's causing this. There's an important feedback process between price movements themselves and the supply and demand.
