How to take a trading position: long or short?

Taking a trading position is the concrete action that transforms your analysis into a real investment. It's the moment when you go from «I think EUR/USD is going to go up» to «I'm actually buying EUR/USD with my money».

Trading strategy

Many beginners think that entering a position is as simple as clicking on «buy» or «sell». In reality, taking a position intelligently requires meticulous preparation and a perfect understanding of the different types of orders available.

Important information: Trading involves risks of capital loss. This article is educational and does not constitute investment advice. Trade only with money you can afford to lose.

In this guide, you'll discover :

  • The difference between long and short positions
  • Essential preparation before each trade (lot calculation, stop loss, take profit)
  • Available order types and their strategic use
  • How to manage an open position intelligently

What does it mean to «take a position» in trading?

Long position

A long position consists of buying an asset in the hope that its price will rise. You are long this asset.

Case in point:

  • You buy EUR/USD at 1.1000
  • You are long the euro
  • If EUR/USD rises to 1.1050, you gain 50 pips
  • If EUR/USD drops to 1.0950, you lose 50 pips.

When to go long :

  • Bullish trend confirmed
  • Technical resistance breached
  • Turnaround after strong support
  • Positive economic news on assets

 

Short position

A short position consists of selling an asset in the hope that its price will fall. You are short this asset.

How it works : With Forex and CFDs, you can sell an asset without owning it. Technically, your broker allows you to take a short position, and you profit from the falling price.

Case in point:

  • You sell EUR/USD at 1.1000 (short position)
  • If EUR/USD drops to 1.0950, you gain 50 pips
  • If EUR/USD rises to 1.1050, you lose 50 pips

 

Notion of buying/selling on markets

In Forex, each pair has two prices:

  • Bid (selling price) Price at which you can sell
  • Ask (purchase price) Price at which you can buy

The difference between these two prices is called the spread, This is your broker's indirect commission.

To remember:

  • Buy = Long position = Bet on the rise
  • Sell = short position = bet on the downside
  • You can win in both directions

Before going into position: what you need to prepare

The risk of making an unprepared position is that you haven't taken one of our training courses. Here are the essential steps before clicking on «buy» or «sell».

Technical or fundamental analysis: spotting an opportunity

Before taking any position, you must have a valid reason for trading based on solid analysis, not intuition.

Technical analysis signals :

  • Break of support or resistance
  • Formation of chartist figures (triangle, head-shoulder)
  • Divergence on indicators (RSI, MACD)
  • Turnaround on psychological level

Fundamental analysis signals :

  • Publication of important economic data
  • Monetary policy decisions
  • Major geopolitical events

Golden rule: Never take a position without at least 2-3 elements to back up your analysis.

Define your risk level and calculate your position size

Before entering a position, you MUST calculate how much you're willing to lose on this trade. This is non-negotiable.

Calculation steps :

  1. Set your % of risk: 1-2% maximum of your capital
  2. Determine your stop loss: the technical level at which you'll be wrong
  3. Calculates the distance: Number of pips between entry and stop loss
  4. Use a batch calculator to determine the exact size

Example with batch calculator :

  • Capital: €1,000
  • Risk: 1% (€10)
  • Distance stop loss: 50 pips
  • Calculated position size: 0.02 lot

At Xenesy, we recommend the systematic use of a batch calculator to avoid sizing errors that can quickly destroy an account.

Defining your plan: TP, SL and exit strategy

Your exit plan must be defined BEFORE you enter the position. Once in position, emotions take over and distort your judgment.

Elements to be defined :

  • Stop loss (SL) Maximum acceptable loss level
  • Take profit (TP) Realistic profit target
  • Risk/return ratio Minimum 1:1.5, ideally 1:2
  • Position management : Partial or total exit

Common exit strategies :

  • One-off take profit
  • Staggered output (50% at TP1, 50% at TP2)
  • Trailing stop to follow the trend
  • Output on opposite technical signal

Order types for entering positions

Understanding the different types of orders is crucial to executing your strategy efficiently.

Market order

The market order is the simplest order: you buy or sell immediately at the posted price.

Advantages :

  • Guaranteed instant performance
  • Easy to use
  • Ideal for immediate entry

Disadvantages :

  • Execution price not guaranteed (slippage possible)
  • Unfavorable for high volatility
  • Wider spread on certain assets

When to use it :

  • Major break in progress
  • Strong signal requiring immediate entry
  • Calm market with low spread

Watch out for slippage: In times of news or high volatility, your order may be executed at a different price than the one displayed.

Limit and stop orders

These conditional orders allow you to enter a position at a specific price, even when you're away from your screen.

Limit order :

  • You buy ONLY if the price drops to your level
  • You sell ONLY if the price rises to your level
  • Guaranteed execution price, non-guaranteed execution

Example: EUR/USD is at 1.1000. You place a limit buy order at 1.0980. The order will be executed only if the price falls to 1.0980 or below.

Stop order :

  • Becomes a market order when the price reaches your level
  • Used to enter a break
  • Near-guaranteed performance, price not guaranteed

Example: EUR/USD at 1.1000 with resistance at 1.1020. You place a stop order at 1.1025 to enter if resistance is broken.

 

Conditional orders: limit stop, trailing stop, OCO

Stop limit order : Combines stop and limit orders. The order becomes a limit order (not a market order) when the trigger price is reached.

Trailing stop : Stop loss that follows the price in a favorable direction. Allows you to capture a trend while limiting losses. Very useful for letting your gains run without constant monitoring.

OCO (One Cancels Other) order: Two linked orders: when one is executed, the other is automatically cancelled.

Example OCO : EUR/USD at 1.1000 in a zone of indecision.

  • Stop order at 1.1020 (bullish break)
  • Stop sell order at 1.0980 (bearish break)
  • As soon as one order is executed, the other is cancelled.

Once the position is open: what can be done?

 

Almost inadvisable: Tracking your position in real time

Why it's tempting:

  • Excitement of seeing profits/losses in real time
  • Sense of control
  • Fear of missing a move

Why it's dangerous:

  • Permanent stress affecting your decisions
  • Temptation to close winners prematurely
  • Risk of moving your stop loss under emotional pressure

Professional approach: Place your stop losses and take profits at the opening, then check them no more than 2-3 times a day. Concentrate on analyzing new opportunities.

Not recommended: Modifying or moving your stop loss / take profit

Dangerous modifications :

  • Move the stop loss further away to «let it breathe».»
  • Reducing take profit through impatience
  • Increasing take profit through greed

Why resist :

  • Your initial plan was defined in cold, unemotional terms
  • Destroy your risk management
  • You turn a small loss into a big loss

The only acceptable modifications :

  • Move stop loss in the direction of profit (breakeven)
  • Partial exit on technical levels
  • Close on strong technical signal to the contrary

Close position manually

Sometimes, manually closing an open position is justified.

Valid reasons :

  • Very strong contrary technical signal
  • News an unexpected game-changer
  • Profit target achieved between SL and TP
  • Changes in market conditions

How to fence :

  1. Make sure it's an objective reason, not an emotional one
  2. Stick to your overall trading plan
  3. Note the reason in your trading journal

My experience with position inputs

After hundreds of positions, here's what I've learned about the art of entering a position effectively.

The error of my ways

For the first few months, I used market orders exclusively out of impatience. The result: discovery of slippage, entries at the wrong price, frustration. When I started using limit orders for my planned entries, my success rate improved by 15%.

My current routine

I never click on «buy» or «sell» without :

  1. Calculated my batch size (even after my experiment, I check)
  2. Placing my stop loss BEFORE entry
  3. Set my take profit at a minimum ratio of 1:2

The type of order I prefer

70% of my positions use deferred orders. I can wait for the best price without stress. The remaining 30% are market orders, only if the market situation and my technical analysis allow it.
