On your commute you scroll past a headline: "AI server stocks surge." One stock has already risen five days in a row. Afraid of missing out, you buy at market during your lunch break, and that turns out to be right around the top of the run. Over the next two weeks it pulls back 12%, and while you sit on the loss, you wonder why you always seem to buy at the peak.
The other scenario is the reverse: you tell yourself, "If it gets back to 290, I'll buy." The day it actually hits 290, you're busy, and by the time you remember, it's back at 320. Chasing highs and missing entries are really the same problem: your entries and exits are based on gut feel, not on prices you wrote down in advance. What Stock Helper does is help you turn that feel into prices, then check them for you every day.
30-Second Overview
| Key point | Details |
|---|---|
| Five RSI(14) zones | Below 30 oversold, 30–50 low range, 50–70 neutral, 70–80 running hot, above 80 extremely overheated |
| The most important rule | Don't chase above RSI 70; never chase above 80 |
| Five prices in every analysis | Buy zone to watch, support zone, resistance zone, stop-loss level, take-profit level to watch |
| Seven action categories | OK to buy, small test position, hold, trim, stop out, don't chase, wait and see |
| How to write your watchlist | Write the watch reason as a price (e.g., "wait for a pullback to 290"), and the morning briefing reviews it for you every day |
| Two discipline rules | RSI is a daily-chart indicator and comes with a reference date; pre-open auction indicative prices are never used |
The Five RSI(14) Zones: Take Its Temperature Before You Buy
RSI (Relative Strength Index) uses the size of gains and losses over the last 14 trading days to produce a number from 0 to 100: the stronger the recent upward momentum, the higher the number; the stronger the downward momentum, the lower it goes. Think of it as a stock's "temperature." It doesn't tell you whether the stock will rise or fall tomorrow, but it does tell you whether it's already running a fever.
Every time Stock Helper analyzes a stock, it shows the RSI value and signal, read in five zones:
| RSI(14) | Zone | Reading | What it means for you |
|---|---|---|---|
| Below 30 | Oversold | May be a good entry point | It's dropped fast and deserves attention, but confirm with support and news. Don't just catch it on sight |
| 30–50 | Low range | A relatively safe buying range | Not yet crowded; a good range to buy in stages according to plan |
| 50–70 | Neutral | Normal fluctuation | Neither cheap nor overheated; let the trend, support, and resistance decide |
| 70–80 | Running hot | Don't chase | It's already had a run; if you want in, wait for a pullback |
| Above 80 | Extremely overheated | Never chase | The risk/reward of chasing is poor; if you already hold it, you can start thinking about taking profits |
Why You Shouldn't Chase Above RSI 70
When RSI shoots above 70 or 80, it usually means the stock has risen a lot in a short time, and most of the people who wanted to buy already have. If you buy now, you're paying the price someone else is willing to sell at, not a bargain price.
The numbers make it clearer (illustrative): a stock climbs from 250 to 300 with RSI at 82. If you chase it at 300, a pullback to around 270, near the 20-day moving average, leaves you down 10%, and it then needs to rise 11.1% just to get you back to even. If you wait for RSI to cool back to around 50 and buy when the price returns to 275, the same drop to 270 costs you only 1.8%.
Overheating signals go beyond RSI. The sentiment analysis watches for signs like "everyone piling in, news everywhere, 'XX concept stocks' all over the place," and flags the risk when they appear. That's usually exactly when you most want to chase, and when you least should.
Support, Resistance, and Moving Averages: Turn "Feels Cheap" Into Actual Prices
Support and Resistance
Support is a price level where buyers tend to step in when the stock falls toward it, often a prior swing low or a heavy-volume consolidation zone. Resistance is the opposite: a level where sellers tend to show up as the stock rises toward it, often a prior high or a zone where a lot of trapped holders are waiting to get out.
Using them is straightforward. If you want to buy, buy near support: if it breaks, you know it's time to leave, so the risk is easier to control. If you want to sell, sell near resistance, or at least don't chase just below it. A break below support or above resistance on heavy volume means the situation has changed, which is why the technical analysis also checks whether volume is expanding.
5-, 10-, 20-, and 60-Day Moving Averages
| Moving average | Common name | What it tells you |
|---|---|---|
| 5-day | Weekly line | The average cost over the past week; reflects short-term strength |
| 10-day | Two-week line | Whether the short-term trend is continuing |
| 20-day | Monthly line | The most common reference for swing trading |
| 60-day | Quarterly line | The medium-term trend; a break below is often seen as a sign of weakening |
A moving average is the average closing price over a period, which you can think of as "roughly the average cost of everyone who bought during that time." When the price is above a rising moving average, most people who bought during that period are in profit. When the price breaks below and the average turns down, more holders are trapped, and rebounds tend to run into selling from people trying to get back to even.
If you swing trade around a day job, here's a useful habit: before buying, check how far the stock is from its 20-day moving average. Far above it with RSI over 70 means you're chasing. Back near the monthly line with RSI between 30 and 50 is a much more comfortable spot.
How the Five Price Points Become Your Order Plan
Every time you ask it to analyze a stock (for example, by saying "Take a look at XXX for me" in Telegram), the trading reference always includes five price points:
| Price point | Meaning | What you use it for |
|---|---|---|
| Buy zone to watch | An entry range with a more reasonable risk/reward | Where to place a limit order, instead of chasing at market |
| Support zone | A range where the price tends to stop falling | Confirming your entry has something to lean on |
| Resistance zone | A range where the price tends to meet selling | The first place to consider selling |
| Stop-loss level | A price that, if broken, means the call is no longer valid | Your exit price, decided before you buy |
| Take-profit level to watch | Where to start considering taking profits | When to take profits in stages, or move your stop up |
Once you have these five numbers, spend two minutes turning them into a plan. Here's an illustrative example: Stock C is at 300, and the analysis gives a buy zone of 288–292, support at 280–285, resistance at 318–322, a stop-loss at 275, and a take-profit level to watch around 320.
- Set your entry price: Don't chase at 300. Place a limit order around 290, possibly in two batches.
- Work out your maximum loss: From 290 to the 275 stop is -5.17%. Can you accept that? If not, buy fewer shares instead of moving the stop farther away.
- Work out your potential gain: From 290 to around 320 is +10.34%. The potential gain is roughly twice the potential loss, which is what makes the trade worth considering.
- Write down what would invalidate it: A break below 275 means support didn't hold, and the reason for the trade is gone. The "conditions under which this call fails" in its risk notes are a direct cross-check.
- Hand the plan over for it to remember: If it hasn't pulled back to 290 yet, add Stock C to your watchlist with the watch reason "Wait for a pullback to 290, stop at 275." Once you've actually bought, tell it in Telegram "Bought one lot of Stock C at 290," then "Set my Stock C stop-loss at 275," and it will alert you if the price breaks that level during the trading day.
That way, the only judgment you need to make during the trading day is whether the price has reached the number you wrote down. All the other thinking was done while you were calm.
Seven Action Categories, and Three Time Horizons
The trading reference also gives a clear category. It's an analytical reference, not an instruction to invest, but it lets you see at a glance where its view lands:
| Category | Usually means | How you can use it |
|---|---|---|
| OK to buy | Price level, trend, and news are broadly supportive | Plan around the five price points; this doesn't mean going all-in |
| Small test position | There's an opportunity, but some uncertainty remains | Start with a small position and add once it's confirmed |
| Hold | The reasons for holding are still in place | Stick to the plan; keep your stop-loss and take-profit as set |
| Trim | Risk is rising, or the stock is overheated after a big run | Reduce the position first and keep some flexibility |
| Stop out | A key level has broken and the call is no longer valid | Follow the exit plan you decided on in advance |
| Don't chase | The stock may be fine, but the price is too high | Put it on your watchlist and wait for a pullback |
| Wait and see | Signals are unclear or data is insufficient | Not acting is also a decision |
The Same Stock Can Get Different Calls on Different Horizons
The trading reference is split into three horizons: short-term looks at price, volume, and how overheated the stock is over the next few days; swing looks at the trend and moving averages over a few weeks to a few months; long-term looks at the company's position in its industry and its fundamentals.
So you might well see a combination like: "Short-term: don't chase. Swing: reassess near the monthly line. Long-term: the industry trend is intact; hold." That's not a contradiction. It's a reminder to be clear about which time horizon you trade on, then read the matching line.
What It Says About the Same Stock at RSI 45 vs. RSI 82
Here's an illustrative comparison showing how the analysis of the same Stock D changes at two different moments. The actual call weighs technicals, news, sentiment, and the broader market together; it never relies on RSI alone:
| Item | At RSI 45 | At RSI 82 |
|---|---|---|
| Price position | Back near the 20-day moving average, holding the prior swing low | A string of gains, far above the 20-day moving average, approaching the prior high |
| RSI reading | Low range, a relatively safe buying range | Extremely overheated, never chase |
| Sentiment | Quiet discussion | News everywhere and concept-stock buzz all over, so it specifically flags overheating risk |
| Possible category | Small test position; possibly wait and see if volume is thin | If you don't own it: don't chase. If you do: possibly hold with a higher take-profit level to watch, or trim |
| Buy zone to watch | Near the support zone, buying in stages | Wait for a pullback to around the 10- or 20-day moving average and for RSI to cool, then reassess |
| Stop-loss thinking | A break below the support zone means the call is invalid | If you chase, a sensible stop is too far below your entry, which is exactly why you shouldn't chase |
It's the same stock and the same company. The only difference is the price you pay and the temperature at which you buy. A good company bought at an overheated price can still leave you stuck for a long time.
Your Watchlist: Write the Watch Reason as a Price
Your watchlist holds stocks you haven't bought yet but want to follow, up to 10. Each one has a "watch reason" field, and how you fill it in determines whether the morning briefing is actually useful to you:
| What you write | What the briefing can do for you |
|---|---|
| "Bullish on AI" | It can only remind you every day that you're bullish on AI; there's nothing to compare against |
| "Wait for a pullback to 290" | It compares against the closing price every day, so you can see at a glance how far off it is |
| "Wait for a pullback to 290 and RSI below 50" | You have both a price and a temperature, which makes it easier to decide when it gets there |
In the morning briefing, each watchlist stock gets one line: the close, the change %, and the watch reason you originally wrote. If you wrote "wait for a pullback to 290" and it closes at 293 one day, you can see immediately that it's only about 1% away and start getting your order ready. If it keeps climbing to 330, you know clearly that it's not your price, and one news headline won't change your mind.
That's how you avoid missing out and avoid chasing at the same time: you set the price in advance, and it checks it for you every day.
Two Discipline Reminders: Don't Decide Based on the Wrong Numbers
Technical Indicators Are Daily and Come With a Reference Date
Indicators like RSI, MACD, and Bollinger Bands are calculated from daily closing prices. During the trading day, today's close doesn't exist yet, so the indicator you see is usually the previous trading day's value. When it cites an indicator, it notes the reference date and won't present yesterday's RSI as the current intraday state.
What that means for you: if RSI was 68 yesterday and the stock is up another 6% intraday today, the real temperature has very likely moved into the running-hot zone. Don't use yesterday's RSI to justify chasing today.
Pre-Open Auction Indicative Prices Are Never Used
Taiwan stocks open at 09:00, and 08:30 to 09:00 is the pre-open auction period. The prices you see during that window are simulated values derived from orders that haven't executed and can be canceled at any time. They aren't anyone's actual trade price.
A real case (2026-08-05): the pre-open auction indicative price showed one electronics stock at -9.84%, close to limit-down, but it actually opened at +3.28%. If you had seen that indicative price at 08:50 and rushed to place a stop-loss order, you'd have sold at a price that didn't exist, in a place you shouldn't have sold. Stock Helper's morning briefing never uses pre-open auction indicative prices and never changes a stop-loss or take-profit call because of them. It's a rule worth following when you watch the market yourself, too.
FAQ
Q: Does RSI below 30 mean I can buy?
Not necessarily. The oversold zone means "may be a good entry point," but a stock that's falling fast can keep falling. It also checks whether support is holding, whether there's negative news, and whether the broader market is weakening. A safer approach is to wait until the price is near support and no clear negative news turns up, then start with a small position according to your plan.
Q: Do the price points it gives change over time?
Yes. Support, resistance, and moving averages all move with the price, and each analysis is a fresh assessment based on the data it finds at that time. If this call differs from the last one, it says so explicitly: "On [date] I suggested X; this time I'm changing it to Y because Z." It won't pretend it never said anything.
Q: How many stocks can I put on my watchlist?
Up to 10 (your holdings list is also capped at 10, separately). Rather than filling it up, include only the stocks you actually have a price plan for, and your briefing will be easier to read.
Q: How do I let it know whether I'm a swing trader or a long-term investor?
Describe your approach in the "Focus and preferences" field in your dashboard, for example: "I prefer swing trading, holding for about 1–3 months. I don't day trade." Click "Save and apply," and starting with your next morning briefing, it adjusts its analysis based on your new settings.
