An oscillator is like that one friend who can't decide between two fav restaurants and keeps oscillating back and forth.
Basically, it’s like a thing that's forever vibing between point A and point B.
Think about it like when you hit up that oscillating switch on your fan and it just can’t pick a lane.
Our technical indicators are kinda like that too—either they're "on" or "off".
Basically, an oscillator’s job is to hit us with a “buy” or “sell” vibe, unless it’s not feeling it and just leaves us on read with unclear signals.Sound familiar? It should! You’ve been here before.
The Williams %R, Stochastic, and Relative Strength Index (RSI) are all part of the squad.
Oscillators work on the idea that as momentum starts to slow, peeps aren’t as hyped to trade at that price if the market’s trending up or down, ya know?
When momentum changes, it’s usually a sign that the current trend is low-key weakening.
These indicators are like the OGs at spotting when the trend’s about to take a U-turn 'cause it's just done living its best life.
Let’s peep a couple of examples.We’ve slapped all three oscillators onto the GBP/USD’s daily chart, and it’s lit.
Remember when we talked about how to work the Stochastic, Parabolic SAR, and RSI? If not, it’s time to hit the rewind button to fifth grade!
Anyway, as you can see, the squad was throwing out buy signals at the end of December like it was hot.
If you hopped on that trade, you’d be bragging about your 400 pips gain. Ka-ching!
Then, in the third week of Jan, the Stochastic, Parabolic SAR, and RSI were all like, “Time to sell!”
And with that mega 3-month drop, you’d have made some serious pips if you went short.
By mid-April, the oscillators were back with more sell signals, making the price do a sharp dive.
Now let’s check out when these oscillators low-key messed up, just so you know they aren’t always the GOAT.In the chart below, it’s like watching them dish out signal drama.
For instance, the Parabolic SAR said “sell” in mid-Feb, but Stochastic was like “nah, buy”.
Who do you trust?
Well, RSI was having its own existential crisis and didn’t give any buy or sell signals.
Check out that chart above, and you’ll see it’s like a false signal party.
During the second week of April, both Stochastic and RSI were like “sell”, but the Parabolic SAR was ghosting.The price kept going up like “don’t mind me”, and you could’ve lost a bunch of pips if you jumped on that short trade.
Another L would’ve been around mid-May if you went with those buy signals from Stochastic and RSI and ghosted the sell signal from Parabolic SAR.
What’s up with these indicators acting sketchy?
The answer is in how they do their math.
Stochastic looks at the high-to-low range in that time frame (like hourly), but it doesn’t care about the hour-to-hour drama.
The Relative Strength Index (RSI) checks changes from one closing price to the next.
Parabolic SAR does its own thing with unique calculations, adding to the chaos.
That’s just how oscillators roll. They assume a price dance always leads to the same reversal.
Of course, that’s straight-up cap.
While knowing why a leading indicator might flop is key, you can’t totally dodge them.
If you’re getting mixed vibes, better to chill than make a wild guess. Don’t force a trade if the chart isn’t hitting all your feels!
