Based on past data, traders can forecast future price changes by employing the field of technical analysis.

You hit the nail on the head. Using past data to pedict future prices is what technical analysis is all about. It's important for traders to understand that this can make predictions more accurate, though it's not foolproof.

Without technical know-how, trading can resemble gambling rather than a methodical approach.

You're absolutely right. This shows why technical analysis is so crucial. It changes trading from random guessing to a more thoughtful and informed process. Knowing these tools helps traders reduce risks and make better decisions.

Indicators and patterns that indicate future market movements are also visible on technical charts.

You’ve got it. Using indicators and patterns helps traders see possible future price movements. By analyzing these, traders can plan strategies to predict market behavior, but it's best to use them with other analysis methods for the best results.

All the best.
