Every trader has that one tool they rely on.
For some, moving averages provide a reliable way to identify momentum shifts, while others can’t trade without Fibonacci levels to pinpoint potential reversals. Some traders swear by RSI or MACD to gauge market conditions, while others prefer the raw simplicity of price action to make decisions.
And while no single indicator guarantees success, finding the one that complements your strategy can make all the difference.
I can’t trade without a price-chart, so that‘s my “top tool”.
I know there are plenty of people who do - and some of them very successfully, for a living - by trading just from the order-book/DoM, which is after all what moves prices. But I can’t. 
If I had to pick an indicator, at the moment I’d say a Keltner channel, which I’m looking at with support and input from @Johnny1974 , to whom I’m grateful. I like the look of it because its bands are ATR-based, in other words it takes volatility into account as well as trend. 
Thank you! 
When I first started, I enjoyed moving averages.
The golden cross seems like a simple strategy.
However, these days, I’m just using price action. Naked charts, as they say.
I couldn’t trade without my shifted Donchian channel.
I trade the fake-outs, as Linda Raschke taught. The opposite of the Turtles’ breakout strategy. I do it from faster charts than recommended, but it still works ok for me.

Hi Ms. @Penelopip,
I can trade without an indicator. I need only candlestick, if it’s considered as tools 
If I am asked to pick indicator, there is no super indicator. I use different indicator on different strategies. Example, when condition is good, RMI or MACD can be money machine on EURUSD M30. In other case, Bollinger Band + ADX will be amazing to use in GBPUSD H1 chart.
I’m wondering to which indicator I should fall in love with 
Whichever one won’t be unfaithful to you, maybe?
A lot of people seem to say good things about ATR? I prefer MFI (money flow index), myself: it’s just a volume-weighted RSI, really. I do sometimes look at that.
Hi @TheodoreThring, 
I don’t have strong chemistry to any indicator yet. 
If I have to choose I will pick RVI. I like the word Vigority on it. 
I also like MFI, it works fine on some instruments. 
Vigority is a skin-care company. In trading, RVI is the relative “vigor” index.
Opss … will I be accused to advertise something here ?
Lol, no, I mentioned it, not you!
For me, the one tool I can’t trade without is the RSI (Relative Strength Index).It’s not just about overbought or oversold levels—it’s about the hidden divergences that often reveal what price alone can’t. RSI helps me stay grounded during volatile swings, especially when noise is at its peak and emotion starts creeping into decisions.
That said, a good tool is only as effective as the ecosystem it operates in. I prefer using platforms that offer clean, regulation-driven infrastructure and transparent market data, which allows indicators like RSI to shine. Whether I’m executing trades on a regulated platform like LCX or analyzing charts through robust interfaces like those available on exchanges such as Kraken, I find that the combination of the right tools and the right environment is key to staying consistent.
After all, it’s not about having the flashiest indicators, it’s about having reliable insights, strong execution support, and the discipline to follow through.
I think, the Fibonacci 38.2, 50.0 & 61.8 retracement levels are good levels to trade towards.
For me, it’s the RSI. It helps me spot overbought or oversold conditions, which makes it easier to decide when to enter or exit a trade.
MACD. It helps me spot momentum shifts and trend changes.
I am use BB, RSI and MA of the most, but not always I looked them but more attention to price pattern.
but, in a strongly trending market, in an uptrend, the RSI will be staying in the overbought area for longer period & in a strong downtrend, it’ll be staying in the oversold area. How do you trade that?
Overbought -Keep buying
Oversold - keep selling 
RSI is the MOST misused indicator!
