Building and Testing a Trading System
Analyzing Like a Technician: Entries and Exits
How technicians turn a chart into a decision — where to get in, where to get out when it works, and where to get out when it doesn't.
From seeing to deciding
Everything so far has been about your eyes. Trends, support and resistance, time frame, moving averages, relative strength — that was all training you to look at a chart and see something structured instead of noise.
Seeing is not deciding. A trend you can identify tells you nothing about whether to act today, at this price, with this much of your money. The rest of this course closes that gap: it turns what you see into rules you write down before you're in a trade and emotional about it.
This lesson is where that starts. It's about the two decisions every trade is made of — where you get in, and where you get out.
The sequence a decision follows
Technicians tend to work through the same three steps, in order:
- Identify the trend. Trade with it, not against it. That's the oldest advice in the discipline, and it's useless until you've actually determined which way the thing is pointed.
- Identify support and resistance. These are the price areas where buying has repeatedly stopped a decline (support) or selling has repeatedly stopped an advance (resistance). They mark where supply and demand pile up — which means they'll either push your trade along or stand in its way.
- Identify the entry and the exit.
Step three is this lesson. Notice that it comes last. You don't go looking for an entry and then work out what the chart is doing; you read the chart first and let it tell you whether there's a decision here at all. Most of the time there isn't.
Entry and exit, not buy and sell
An entry is when you open a trade. An exit is when you close it.
Technicians use those words instead of "buy" and "sell" for a specific reason: which one you do depends on which direction you're betting. In a long trade — a bullish one — you buy to open and sell to close, hoping to sell higher than you bought. In a short trade — a bearish one — it runs backwards: you sell shares you've borrowed from your broker to open, and buy them back to close, hoping to buy lower than you sold. "Buy" means open in one and close in the other. "Entry" and "exit" mean the same thing in both, so that's the vocabulary.
Two signals, two directions
Support and resistance are actionable precisely because they're where supply and demand collect. They give you two signals, and each has entries and exits attached:
- A break — price cuts through the level and keeps going.
- A bounce — price reaches the level, fails to get through, and turns back.
Bullish and bearish entries are built from those two. The bullish pair: enter at a break of resistance, or enter on a support bounce. The bearish pair mirrors it: enter at a break of support, or enter on a resistance bounce.
Entering on a break of resistance
Say fictional XYZ has spent months moving sideways, turning back every time it reaches about $50. That's resistance — a ceiling sellers keep defending. Then one day it closes at $50.40, above the ceiling, at a new high.
A breakout is price moving decisively through support or resistance. To a technician, this one says the sellers who were sitting at $50 have been used up: demand finally exceeded the supply parked there. For a short- or intermediate-term trader, that's a bullish entry signal.
Figure
Volume matters here. A break on heavy volume means a lot of shares changed hands to get through the level, which is more convincing than a drift through on a quiet afternoon. It isn't a requirement — breaks happen on ordinary volume and go on to work — but it's evidence.
Entering on a support bounce (CAHOLD)
The other bullish entry waits for price to fall to support and refuse to go lower.
The problem is knowing when the fall has stopped. A low is obvious in hindsight and invisible while it's happening — every falling stock looks like it's found the bottom right up until it doesn't. Technicians use a mnemonic to make the judgment mechanical: CAHOLD, a Close Above the High Of the Low Day. Find the day with the lowest low. When a later day closes above that day's high, the bounce is confirmed and that's your entry.
Drawing the support line first is what makes this workable. It gives you a price area where a low is plausible, so you're not applying the rule to every dip in a free fall.
There's a nice wrinkle worth knowing. After XYZ broke through $50, that old ceiling often becomes the new floor — the level where sellers used to wait becomes the level where buyers now step in. So a pullback to around $50 that prints a CAHOLD is a second entry, off the same line, now doing the opposite job.
Figure
Bearish entries
The bearish signals are the same two shapes upside down. Fictional ABC has held a floor near $46 for months; one day it cuts below on heavy volume. That's a support break — supply overwhelmed the buyers who'd been defending the level — and it's the bearish counterpart to a resistance break.
The bearish bounce has its own mnemonic: CBLOHD, a Close Below the Low Of the High Day. Price rallies into resistance, fails, and when a later day closes below the high day's low, the bounce down is confirmed.
Read these signals. They tell you a trend has likely turned, and that's information whether or not you ever place a bearish trade — for most readers, the useful response to a support break in something you own is the exit rule you already wrote, not a short position.
The breakout that doesn't break out
Here's the thing the charts in every lesson quietly hide: they're finished. You're looking at the answer.
At the right edge of a live chart, a breakout and a false breakout — price pushing through a level and then failing back inside — look identical. Both are one close on the wrong side of a line. The difference only appears over the following days, and by then you're already in.
False breakouts are common. They are not an exotic failure mode; they are a normal Tuesday. Price pokes above resistance, the buying dries up, and it slides back into the range — sometimes straight through the other side.
So run the XYZ example again with the ending changed. You entered at $50.40 on the break. Instead of climbing, XYZ drifts back to $49, then $48, and a week later it's at $42, well below the range it spent months in. Nothing about your entry was wrong: the signal was real, you followed your rule, and you lost money anyway. That's not a mistake you can eliminate with a sharper eye. It's the cost of doing this, and the only thing that decides how much it costs you is the exit you set before it happened.
Exits: the half that decides whether you keep your money
Entries feel like the decision. They're the exciting part — the moment you pick, the moment you're right. Exits feel like paperwork.
It's backwards. Your entries determine which trades you're in. Your exits determine what you keep. A trader with mediocre entries and disciplined exits survives; the reverse doesn't, and it doesn't take long.
There's a plain reason to decide exits in advance, and it isn't about discipline as a virtue. You cannot think clearly about money you are currently losing. Watching a position go against you is the single worst condition under which to make a decision about it, and it's exactly the condition you'll be in when the decision arrives. Every argument for holding on sounds excellent while you're down. Deciding at the start — while it costs nothing to be honest — is how you get the judgment of a calm person applied to a moment when you won't be one.
Two exits, one for each way a trade can end.
The target: the exit when it works
A target is a price at which you plan to close a winning trade. It isn't an order sitting at your broker; it's a reference point in your rules, a number you decided on when you had no stake in the answer.
One common way to set it: measure the distance from support to resistance, and add it to the breakout level.
Back to XYZ. It ranged between support at $40 and resistance at $50 — a height of $10. It broke resistance, so the target is $50 + $10 = $60. If price reaches $60, you place the order and you're out.
| Support | $40 |
| Resistance | $50 |
| Height (resistance − support) | $10 |
| Entry (close on the break) | $50.40 |
| Target (resistance + height) | $60.00 |
Those numbers are round because they're illustrative, not because ranges are tidy. Note what the target really is: a decision to stop being greedy, made in advance by someone who isn't yet greedy.
Targets suit short-term traders. Long-term investors often skip them entirely — a target caps a winner, and letting winners run is most of the point when you hold for years. They tend to use a trailing stop instead, below.
The stop: the exit when it doesn't
A stop order is different in kind. It's an actual standing order at your broker, placed right after you enter: if price hits the level you set, a market order triggers and your position closes at the next available price.
Long positions use a sell-stop, because selling is how you close a bullish trade. Short positions use a buy-stop. The glossary calls the bullish version a stop-loss order; it's the same instrument.
Two honest caveats. A stop doesn't prevent a loss — it takes one, on purpose, to prevent a bigger one. And it closes at the next available price, not at your number: in a fast drop, that can be meaningfully worse than the level you set. A stop is a limit on how long you stay wrong, not a guarantee of the price at which you stop being wrong.
Where to put it
This is a genuinely hard tradeoff, and nobody can hand you the answer.
You want the stop where you'd be confident the trend has actually turned — without having to lose much to find that out. Those two goals fight. Put it too close and ordinary wiggle knocks you out of trades that would have worked, repeatedly, each time for a small loss that adds up. Put it too far and you're right about the exit but you paid too much for the information.
One author's sample rule looks like this:
"Set a sell-stop order 3% below support upon entry."
Treat that as an illustration of what a written rule looks like, not a law. The 3% isn't measured from anything — it's an editorial choice about how much room to give the stock, and reasonable people place stops in a range of a few percent on either side of that. The thing worth copying is the shape: a specific level, a specific reference point, decided at entry, written down. The number is yours to reason about and to test.
Apply it to XYZ. You entered at $50.40 on the break of $50, and old resistance becomes your new support at $50. Three percent below is $48.50 ($50 × 0.97). That's your sell-stop.
Now play both endings.
It works. XYZ climbs, reaches $60, you exit at your target. You risked about $1.90 a share to make about $9.60.
It doesn't. The breakout was false. XYZ falls back, and at $48.50 your stop triggers; the position sells at the next available price — call it $48.30. You're out at a loss of roughly $2.10 a share. XYZ then keeps sliding to $42. Your rule cost you $2.10 and saved you $8.
That second ending is the one to sit with. The rule didn't make you money. It capped what a normal, unremarkable losing trade could take from you, and it did it without asking you to be brave while your money was disappearing.
The bearish rule mirrors it: "Set a buy-stop order 3% above resistance upon entry" — same shape, same caveats, same asymmetry warning from earlier.

This lesson explains the idea in full without it.
Long-term investors who don't use targets need something that protects gains without capping them. That's a trailing stop: a stop you move up as the price climbs, and never move down.
Picture the stock climbing a building, making floors and ceilings as it goes. You keep the stop a floor or two below where price currently is — close enough to protect what you've made, far enough that ordinary fluctuation doesn't reach it. Each time it climbs to a new floor, the stop comes up behind it. You can do this by hand or your broker may do it for you.
The whole discipline is in the second half of the definition. When price falls, the stop does not move. Lowering a stop to give a losing position "room to work" is the same act as having no stop at all, performed at the exact moment you're least equipped to judge it. If you're going to move it down, you never had a rule — you had a hope with a number attached.
Key takeaways
- Read the chart before you look for a trade: trend first, then support and resistance, then entries and exits. Most charts don't produce a decision.
- Support and resistance give two signals in both directions — a break through the level, or a bounce off it. The bullish entries are a break of resistance and a support bounce (CAHOLD: a Close Above the High Of the Low Day). The bearish ones mirror them (CBLOHD: a Close Below the Low Of the High Day).
- Breakouts are only obvious afterward. False breakouts are ordinary, not exotic, and a real signal you followed correctly can still lose money. That's the cost of the method, not a mistake in it.
- Exits matter more than entries. A target is your exit when a trade works; a stop order is your exit when it doesn't. A stop takes a small loss on purpose to prevent a large one, and it fills at the next available price, not necessarily yours.
- Decide both exits before you enter, because you cannot think clearly about money you're currently losing. Specific rules like "3% below support" are one author's illustration to reason about and test — the discipline is in writing a rule down and not moving it when the position turns against you.
