How to Use the Long/Short Tool Step-by-Step
What Is the Long/Short Tool in Trading?
The long/short tool is a visual planning tool used on charting platforms like TradingView to map out a trade before entering.
· It shows your entry, stop loss, and take profit levels
· It calculates your risk-to-reward ratio
· It helps you plan trades instead of reacting emotionally
Do you ever look at a chart and realize you have no clear plan for where to enter, exit, or manage risk?
If you’ve ever clicked "buy" or "sell" based on a feeling, only to panic the moment price moves against you, you’re not alone.
Most people starting their journey as beginner day traders skip the most important step: the architectural phase. They see a candle move and react, rather than seeing a setup and planning.
At The Agorion Collective, we believe that the difference between gambling and trading lies in structure. Before you ever put capital at risk, you need a visual map of what you expect to happen. This is where the long/short tool comes in. It isn't a magic indicator that tells you where the market is going; instead, it is a planning tool that forces you to be honest about your risk before you step into the arena.
This article is part of the Agorion Foundations Series, where we break down the core concepts of trading step-by-step for beginners. Each lesson builds on the one before it so you can develop real market understanding instead of jumping between disconnected strategies. By mastering this tool now, you are learning how to "count" your risk before you ever try to do the complex "math" of advanced strategies.
What Is the Long/Short Tool in Trading?
The long/short tool is a visual overlay used on charting platforms like TradingView to map out a potential trade. It consists of two colored boxes, usually green for your profit target and red for your risk, centered around a specific entry price. When you are learning how to start day trading, this tool serves as your "pre-flight checklist." It takes the abstract numbers of a trade (price levels and percentages) and turns them into a clear, visual representation on your screen. If you want the foundational overview first, read our introductory guide on what the long/short tool is before diving into this step-by-step how-to article.
What it does: It calculates your risk-to-reward ratio and visually displays where you will exit the trade, whether you win or lose.
Why it matters: It removes the guesswork. You see exactly how much "room" you are giving the market to move before you admit the trade didn't work.
How beginners misuse it: Many new traders treat the tool like a signal, thinking that because they drew it, the market must follow it. In reality, the tool is for you, not the market. Others place the tool on the chart only after they’ve already entered a trade, which defeats the purpose of planning.
Visual: A green and red block is a blueprint with measurements being taken, representing the mapping of your trades before you enter the market.
Why the Long/Short Tool Matters for Beginners
We often talk about the philosophy of Clarity Before Complexity. In the early stages of your education, your biggest enemy isn't the market, it’s your own emotions. When real money is on the line, the human brain tends to focus on the "green" (the potential profit) while ignoring the "red" (the potential loss).
Using the long/short tool forces a shift in perspective. By drawing the trade out first, you are:
Visualizing Risk vs. Reward: You can see if the "win" is actually worth the "risk." If your red box is twice as big as your green box, you can see instantly that the trade doesn't make logical sense.
Planning Before Execution: It creates a "buffer" between seeing a move and clicking a button. This brief moment of planning helps settle the nervous system.
Removing Emotional Decisions: Once the tool is set, your "rules" are visible. You’ve decided where you are wrong (the stop loss) before the trade even starts. This prevents the common mistake of moving your exit point further away out of hope or fear.
How to Use the Long/Short Tool Step-by-Step
Whether you are using a Tradingview chart or another platform, the mechanics of the tool are generally the same. Here is how we recommend using it to build a structured plan.
Step 1: Identify Your Entry Point
Before you touch the tool, you should have a reason to enter based on what you’ve already learned in what a trending market looks like. Once you see a setup, select the "Long" tool (if you think price is going up) or the "Short" tool (if you think price is going down). Click on the chart at the exact price where you intend to enter.
Step 2: Set Your Stop Loss
The red portion of the tool represents your stop loss, the point where you admit the trade is no longer valid. Drag the edge of the red box to a logical level. In the Agorion Foundations, we teach you to place this where the price structure would be "broken" if it reached that point.
Step 3: Set Your Take Profit
The green portion is your target. Drag this to the level where you want to lock in your gains. Instead of picking a random number, look at previous price action or candlestick patterns to see where the price might naturally pause or turn around.
Step 4: Evaluate Your Risk-to-Reward
Look at the center of the tool. It will show a number (e.g., 2.0). This means for every $1 you risk, you stand to make $2. As a beginner, this number matters more than the outcome of any single trade. It tells you whether the trade makes sense before you take it.
Think of It Like This
Imagine you are planning to build a house. You wouldn't just show up to an empty lot with a truckload of bricks and start stacking them, hoping a kitchen eventually appears. You would start with a blueprint. You would know exactly where the foundation ends and where the roof begins before a single brick is laid.
In trading, the long/short tool is your blueprint. Entering a trade without it is like trying to drive to a new city without a map or GPS. You might get there eventually, but you’ll likely waste a lot of fuel (capital) and experience a lot of unnecessary stress along the way. Planning is the "map" that ensures you know exactly where you are going, and where you need to turn back if you get lost.
Common Beginner Mistake: Planning After Entering
The most frequent mistake we see is "Post-Entry Planning." This happens when a trader sees the price moving fast, feels the "FOMO" (fear of missing out), and enters the trade immediately. Only after the trade is active do they pull out the long/short tool to see where they "should" have put their stop loss.
By then, the damage is often done. Your emotions are already high because your money is moving. When you plan in reverse, you tend to adjust the tool to fit your entry, rather than adjusting your entry to fit a logical plan.
Another mistake is focusing only on the green box. Beginners often stretch the green box higher and higher, imagining huge profits, while keeping the red box tiny. This results in getting "stopped out" of trades constantly because the market didn't have enough room to breathe. Proper Risk Management Fundamentals require a balance between the two.
Where This Fits In Your Learning Process
If you’re just starting out, the long/short tool is one of the first ways you move from understanding the market to interacting with it. It turns ideas into decisions and decisions into structure.
That’s where real progress begins.
Start Planning Before You Trade
If you’ve been entering trades without a clear plan, you’re not alone.
Most beginners are never taught how to plan a trade before they enter. They’re taught strategies, but not the discipline behind execution.
The goal isn't to be right every time. The goal is to have a plan every time. When you have a plan, a losing trade is just a piece of data. When you don't have a plan, a losing trade feels like a personal failure.

Summary
The long/short tool is not a strategy, it’s a way to bring structure into your trading.
Before entering a trade, you should always know:
- where you plan to enter
- where you will exit if you're wrong
- where you will take profit if you're right
The goal isn’t to predict the market perfectly. It’s to approach every trade with a clear plan instead of reacting in the moment.
Frequently Asked Questions
Do I need the long/short tool to trade?
Technically, no, you can enter price levels manually into your broker. However, for beginners, we consider it essential. It helps you visualize the "space" of the trade and plan your risk-to-reward ratio clearly before you ever commit capital.
Is the long/short tool a strategy?
No. The long/short tool is a planning and visualization tool. A strategy tells you when and why to enter; the tool helps you decide how to manage that entry once you've found it.
Can I use the long/short tool on any market?
Yes. Whether you are looking at stocks, forex, or crypto, the principles of price action and risk management remain the same. The tool works on any chart.
Should I use it before every trade?
Yes, especially as a beginner. Making this a non-negotiable part of your process builds the muscle memory of discipline. Eventually, you will find that you can't imagine entering a trade without seeing the "map" first.
