Yes, most indicators are good and you can trust 100% on them. The great thing about every indicator is that they show you what has already happened.. You can see at the glance and at multiple time frames what has happened in the past relative to whatever indicator you are using. The great thing about an indicator is that it will always show you only what has already happened. The whole point of using any indicator is based on the belief that history tends to repeat itself. It is true for technical analysis in geneeral.

Forex indicators are of great importance, but you cannot really trust them completely. Yes they are quite accurate, but you should not rely on them only. Indicators are there to serve as a helping hand, so to speak. As a trader you can use them and what they are indicating but you should also use your other knowledge along with analysis and align everything to your strategy.

Trusting a forex indicator 100% is not advisable. Forex indicators, such as moving averages, RSI, and MACD, are tools designed to help traders analyze market trends and make informed decisions. However, no indicator can guarantee accuracy all the time due to the inherently unpredictable nature of the forex market. Market conditions, geopolitical events, and economic data releases can cause sudden price movements that indicators cannot foresee.

Additionally, indicators often rely on historical data, which may not always predict future market behavior accurately. It's essential to use indicators as part of a broader trading strategy, incorporating risk management and fundamental analysis. Diversifying your approach and being aware of the limitations of each indicator can improve your chances of success, but expecting any single indicator to be infallible can lead to significant losses. Therefore, while indicators are useful, they should not be solely relied upon for trading decisions.
