How to Build a Set of Indicators Without Overdoing It

It's common to see a beginner's chart with seven or eight overlapping indicators, all flashing different signals at once. The intention is good: looking for more confirmation before trading. In practice, the result tends to be the opposite: more confusion, not more clarity.

The problem is rarely a lack of indicators. It's not understanding that many of them, despite having different names, measure essentially the same thing.

The four families of indicators

Before choosing any indicator, it helps to know which family it belongs to. Most technical indicators fall into one of these four categories:

• Trend: help identify the price's overall direction, like moving averages and the MACD.
• Momentum: measure the speed and strength of a move, like the RSI and the stochastic.
• Volatility: show the size of price swings, like Bollinger Bands and the ATR.
• Volume: show the participation behind a move, like plain volume and indicators derived from it.

The most common mistake: stacking indicators from the same family

Using the RSI and the stochastic at the same time, for example, seems to add a second opinion. In practice, the two measure momentum in similar ways, so they tend to agree most of the time. This creates a false sense of confirmation: two indicators pointing the same direction look more reliable than one alone, but if both come from the same family, that confirmation is largely redundant.

The same applies to using three different moving averages at once: they'll essentially tell the same trend story, just with slight lags between them.

How to build a set that actually complements itself

A more efficient way to build a set of indicators is to choose, at most, one representative from each family, based on what the strategy actually needs:

• A trend indicator, to know which direction to trade in favor of.
• A momentum indicator, to assess whether the move still has strength or is already running out of steam.
• A volatility indicator, to calibrate the size of the stop-loss and the position.
• Volume, to confirm whether a breakout or reversal has real participation behind it.

With this combination, each indicator answers a different question, instead of repeating the answer of another one already on the chart.

Practical example of a combined reading

Imagine an asset in an uptrend, according to a long-term moving average. The RSI, a momentum indicator, is rising but not yet in overbought territory. Bollinger Bands, a volatility indicator, are narrowing, suggesting a possible expansion of movement soon. Volume has been growing on the last up candles.

In this scenario, the four signals tell a consistent story: uptrend, healthy momentum, potential for expanding movement, and real buyer participation. That's different from simply seeing the RSI and the stochastic rise together, which is basically the same information repeated twice.

Indicators lag: that's not a flaw, it's a feature

Practically every technical indicator is calculated based on prices that have already happened, which means it always reacts with some delay relative to the actual price movement. That doesn't invalidate the use of indicators, but it explains why they work best as a context and confirmation tool, not as a crystal ball.

How to apply this to your chart

Review the indicators you already use today and classify each one into one of the four families. If you notice two or more indicators from the same family on the chart, consider removing one of them and, if it makes sense, replacing it with an indicator from a family that isn't represented yet.

No combination of indicators guarantees a winning trade: they organize information and help you make more informed decisions, but the final outcome of any trade, whether on Astron or any other platform, remains subject to the risk of loss, especially in markets that move suddenly and unpredictably.

A good test to check whether your chart is overloaded is this: cover half the indicators and see if your decision to enter or not enter a trade would change much. If the answer is no, some of them are probably just repeating information, and a cleaner chart, with one representative from each family, tends to make reading easier without losing analytical quality.
