Moving Averages --- Your First Real Tool

By the first week of December, Rohan's TradingView chart looked like a circuit board.

Over the previous two weeks he had added nine indicators: RSI, MACD, Bollinger Bands, two moving averages, a volume oscillator, Stochastic RSI, Average True Range, and something called the Ichimoku Cloud, which he'd added because a YouTube comment called it "the most powerful indicator in existence."

The price chart itself was barely visible underneath it all. The main panel had four overlapping lines in different colours, crossing each other at random intervals. Below it sat three sub-panels of histograms and oscillators, each with its own scale and rhythm, each seemingly unrelated to the others.

He stared at this chart for forty minutes and still couldn't say, with any confidence, whether the stock was going up, down, or sideways.

He took a screenshot and sent it to Meera.

She replied in thirty seconds: This is a cry for help.

He brought the screenshot to KM Sir on Sunday.

KM Sir looked at it for a moment. He picked up his filter coffee, set it down without drinking it, picked up his notebook, read yesterday's line, and set it down.

*A lagging tool that confirms is worth more than a leading tool that guesses.*

"How many of these indicators do you understand?" KM Sir asked.

Rohan considered being honest. He was honest. "Two. Maybe."

"Remove the ones you do not understand."

He removed seven indicators. The chart became readable.

The two he kept were the 20-period EMA and the 50-period EMA. He had added these after reading about moving averages, and had some grasp of what they showed him, even if he couldn't explain it precisely yet.

Moving averages, KM Sir explained, were the simplest and most durable tool in technical analysis. Their logic was also their limitation, and he needed to understand both.

A moving average calculates the average closing price over a set number of periods. A 20-period moving average adds the last twenty closing prices and divides by twenty. As each new candle closes, the average moves forward, dropping the oldest price and adding the newest. The result is a smooth line on the chart, showing the average direction of price over that stretch.

There were two main types: the Simple Moving Average, which weighted all periods equally, and the Exponential Moving Average, which gave more weight to recent prices. The EMA reacted to recent price changes faster than the SMA. For traders who wanted to track current momentum closely, the EMA was generally more useful.

The two most commonly used for swing trading were the 20 EMA and the 50 EMA. The 20 EMA tracked shorter-term momentum --- what price had been doing over roughly the last month. The 50 EMA tracked medium-term momentum --- what price had been doing over roughly the last two months.

"When price is above the 50 EMA and the 50 EMA is sloping upward, the trend is generally up," KM Sir said. "When price is below the 50 EMA and the 50 EMA is sloping downward, the trend is generally down. That's a simple statement, and it's roughly correct in trending markets."

"Approximately?"

"Moving averages lag. They tell you what has happened, not what will happen. By definition, the 50 EMA includes data from fifty periods ago. By the time the 50 EMA has confirmed a new uptrend, price has already moved a good distance in that direction. You're paying for confirmation with part of the move."

Meera had asked the right question before Rohan even got to it. When he relayed it to KM Sir that afternoon --- if it lags, why use it? --- KM Sir gave an answer that changed how Rohan thought about tools in general.

"Because a lagging tool that confirms is worth more than a leading tool that guesses," he said. "You can find plenty of indicators that claim to predict where price will go. In my experience, most of them are coincidences in historical data. A moving average doesn't claim to predict. It confirms. It says: this has been the direction of price for this period. Is that consistent with the trade you're considering?"

"So it's not a signal. It's context."

"It's a filter. Before taking a trade, you ask: is price above or below the 50 EMA? Is the 50 EMA sloping in the direction of my trade? If yes, that's one piece of confirmation. If no, you need a compelling reason to go ahead anyway."

Rohan thought about the nine trades he had lost in the downtrend the month before. He pictured the chart: price below the 50 EMA, the 50 EMA sloping downward. He had bought anyway.

"I would have failed the filter on all nine," he said.

"Yes."

There was one more idea connected to moving averages that KM Sir mentioned but didn't dwell on: the Golden Cross and the Death Cross. When the shorter moving average crossed above the longer one, that was considered bullish --- the Golden Cross. When the shorter crossed below the longer, it was bearish --- the Death Cross.

These signals were well known, and because of that, their track record was mixed. Since so many traders acted on a Golden Cross, the signal could become self-fulfilling: price moved up simply because everyone watching for it bought. It could also fail completely if the cross happened during a sideways, choppy market.

"These crossovers are worth knowing," KM Sir said. "They're not worth trading mechanically. They're one piece of information, not a complete system."

Rohan wrote this down. He had noticed, over the past few weeks, that KM Sir never presented anything as a complete system. Every tool had a context where it worked and a context where it failed. Every rule came with a condition attached. At first this had been frustrating --- he had come to KM Sir looking for rules. He was starting to understand that the rules were always conditional.

He removed seven of the nine indicators and kept only the two EMAs. The chart was clean now. He could see the price, the two moving averages, and the volume panel.

Looking at the current chart, he could see the 50 EMA beginning to slope upward for the first time in six weeks. Price was approaching it from below.

He didn't place a trade. He had learned enough by now to know that one condition wasn't a reason. He needed more before he entered.

What "more" meant, exactly, was the subject of the following Sunday.

The filter coffee KM Sir had placed on the table at the start of the session sat untouched beside him until the end. He never noticed it go cold. Rohan had watched it happen over two hours and said nothing.

He didn't know why this detail stuck with him. But it did, for years.

The reason he had added nine indicators before understanding what any of them did was the same reason most retail traders make the same mistake: he had been looking for certainty.

Each indicator promised to show him something the price alone couldn't. RSI promised to show when something was overbought or oversold. Bollinger Bands promised to show volatility. Stochastic promised to show momentum. The Ichimoku Cloud --- the most complex of the nine --- had promised, according to that YouTube comment, to show trend direction, momentum, support, resistance, and signal timing, all at once.

The problem was that every one of these promises came with conditions. RSI above seventy meant overbought --- in a ranging market. In a strong uptrend, RSI could sit above seventy for weeks. Bollinger Bands narrowing signaled low volatility and a likely expansion --- but not which direction the expansion would go. Every indicator that claimed to tell him what was coming was, on closer inspection, telling him something about what had already happened, and leaving the future to him.

He had added nine indicators because he thought more information would mean more certainty. What he'd actually produced was more noise.

Two indicators, understood well and used in the right context, were worth more than nine indicators understood poorly.

KM Sir spent part of that Sunday on an idea Rohan hadn't heard before: the difference between a leading indicator and a lagging indicator.

A leading indicator tries to predict where price will go. By definition, it has to be based on something other than price itself --- or on price patterns that have historically shown up before a move. Leading indicators were exciting because they offered the chance to be early. They were dangerous because the patterns they relied on were statistical tendencies, not laws, and they threw off plenty of false signals.

A lagging indicator follows price. It confirms what price has already done. It tells you a move happened with enough force and duration to show up in its calculation. The moving average was the clearest example: it could only confirm a trend after the trend had already established itself. Its value wasn't prediction, but filtering --- it helped him avoid fighting an established trend.

"Most retail traders prefer leading indicators," KM Sir said. "Because they want to be early. They want to buy the bottom and sell the top. They think this is possible consistently. It is not. The traders who have been doing this successfully for a long time prefer confirmation. They accept that they'll miss the first part of a move. They trade the part of the move they can confirm."

This became the underlying principle of Rohan's system. Not to predict. To confirm, then follow.

He asked KM Sir a question he'd been sitting with for a week: was there a perfect number of indicators?

KM Sir thought about it the way he thought about most things --- without hurrying, without giving the impression the answer was already on its way.

"There is a number that is too many," he said. "There is a number that is enough. They're different numbers for different traders and different methods. What I can tell you is the principle: every indicator you add has to answer a question your existing setup can't already answer. If you already know the trend direction, you already have a signal, and you already have volume confirmation --- what does a fourth indicator add? If the answer is nothing, don't add it."

"My system right now has the 50 EMA for trend, and volume," Rohan said. "But I still need something for the signal. Something that tells me when momentum in the direction of the trend is showing up."

KM Sir nodded. This was the question that led into the next chapter.

The MACD was the answer --- a momentum indicator built from moving averages, designed to show exactly when shorter-term momentum was lining up with a longer-term trend. Rohan didn't know this yet. He left the Sunday session with the question unresolved, but with a clearer sense of what he was looking for: not another filter, not another confirmation. A signal. Something that told him when to act within the conditions the trend and volume had already set up.

He spent the week looking for it. He found it Thursday evening, in a description of the MACD that finally explained not just what it showed, but why it worked. He read it three times. Friday morning he added the MACD to his chart and removed the other seven indicators.

The chart was readable again. The MACD panel below the price told him what the relative position of two EMAs was saying about current momentum. He sat with this for a day before building anything on top of it.

Saturday morning, before 6am, he opened his notebook.
