Happy Wednesday, tradersβ¦
Ben here.
In a recent SPYDER Live Workshop, I talked about technical analysis and its importance for options traders.
I mentioned several technical indicators I place on my charts, including:
- 200-day simple moving average (SMA) β The average price of the stock over 200 days, visualized as a βmovingβ line on the chart.
- 14-day relative strength index (RSI) β A momentum oscillator that measures the speed and change of price movements. RSI reads as a number between 0 and 100. (RSI is usually considered overbought when above 70 and oversold when below 30.)
- Average true range (ATR) β The average of true ranges over the specified period. This measures volatility while considering any gaps in the price movement.
- Volume profile β The volume traded at various price levels over a specified period.
But the truth is, thereβs one technical indicator that trumps all of the others.
This indicator is a secret weapon, giving you a clear visual representation of a chartβs overall trend.
The vast majority of traders donβt even know this secret weapon exists.
But if you learn to employ it, you can potentially create an edge for yourself and exponentially improve your trading performance.
Today, Iβll show you how utilizing this one technical indicator can change your trading foreverβ¦
How The 21-day EMA Works
A huge part of trading is accurately identifying trendlines.
Stocks tend to get stuck in both uptrends and downtrends, depending on how traders feel about the name.
If youβre trying to long a stock (or trade call options) β you must know where the trendline is.
And the same goes if youβre trying to short a stock (or trade put options).
Some traders draw their own trendlines on charts, which can work for someβ¦
But over the years, Iβve discovered that the 21-day exponential moving average (EMA) does most of that work for you.
Time and time again, I see the 21-day EMA acting as support for uptrends (and as resistance for downtrends).
By paying attention to the 21-day EMA, you can take most of the guesswork out of identifying your uptrends and downtrends.
Letβs look at some examplesβ¦
Identifying Uptrends
NOTE: For all of the following examples, the 21-day EMA will be represented by the yellow line.
I want to show you how the 21-day EMA can confirm a bullish uptrend:

Since the beginning of 2024, the 21-day EMA line on the Boston Scientific Corporation (NYSE: BSX) chart has been a perfect indicator.
It confirms the uptrend and gives you a visual illustration of the chartβs direction.
Every time the chart reverted back to (or just below) the trendline, that was a screaming buy signal for a swing trade.
Same thing on this eBay Inc. (NASDAQ: EBAY) chartβ¦

The price action lines up with the 21-day EMA like theyβre married to each other.
So, letβs say you wanted to get in on EBAY calls anywhere in this trendline.
The only thing you wouldβve needed to do was wait for the chart to re-test the 21-day EMA, then enter.
Contrarily, if you see a chart thatβs overextended beyond the trendline β be patient and wait for the mean reversion before buying your calls.
However, the best part of this indicator is that it works on both sides of a trendβ¦
Identifying Downtrends
βBut Ben, Iβm a huge bear and I want to buy puts. Does this indicator work for downtrends as well?β
It sure doesβ¦

In an almost mirror-inverse chart to EBAY, Intel Corp. (NASDAQ: INTC) has been stuck under the 21-day EMA downtrend for over a year.
As you can see, every time INTC tries to crack the yellow line β it gets brutally rejected.
Again, you couldβve used this indicator to know when and where to buy puts. As soon as the chart neared the yellow line β that was a signal to buy puts.
Same with this LULU chartβ¦

Look back at Januaryβ¦
Had you noticed the chart losing the 21-day EMA and bought puts at that moment, you couldβve made a fortune holding those contracts over the entire year.
And you couldβve done the same in mid-Marchβ¦
The 21-day EMA is a magic line for identifying uptrends and downtrends.
Add this indicator to your charts and use it as a barometer for how close to (or far away) a chart is from its overall trend.
Bottom Line: This is a game-changer when implemented correctly.
Before we go, letβs look atβ¦
