Why a wider spread makes it harder to win
In FX, you start with a loss equivalent to the spread at the moment you enter a position.
For example,
- Spread is 1.0 pips
- Profit target is 5 pips
versus
- Spread is 5.0 pips
- Profit target is 5 pips
the difficulty is completely different.
The wider the spread, the more price movement is required to reach profitability, and the greater the impact on short-term trading.
Therefore,just widening the spread can significantly change win rate and profitability.
Spreads can widen over the weekend
Please be especially careful on weekends.
In MT4, when the market is closed,the Friday close spreadis shown.
At this timing, spreads are often much wider than usual.
If you start the tester as is,
- you may experience a large initial loss right after entry
- profits are hard to achieve
- win rate drops drastically
this state can occur.
When practicing on weekends, please check the strategy tester’s spread value first.

Adjust to match your practice goals
Spreads can adjust the difficulty of practice.
■Beginner・Practice-focused
If the goal is simply to get used to trading, it is recommended to set a smaller spread.
This reduces unnecessary handicaps, allowing you to focus on chart reading, entry, and exit practice.
■Practice close to real trading
If you want to practice in an environment close to real trading, adjust to a spread close to what your actual broker uses.
You can practice with a feel close to real trading.
Feel the effect by changing the spread
Please try,
- small spread
- typical spread
- large spread
with each, using the same method.
Even with the same trade,
- win rate
- profit
- risk-reward ratio
- psychological margin
will differ significantly, I believe you will feel the changes.
The spread is like a “fee.”
It is not often consciously considered, but it is a very important factor that can influence results, especially in scalping and day trading.
Helpful for choosing a broker as well
Spreads vary by broker.
Even for the same currency pair,
- narrow-spread brokers
- wide-spread brokers
can lead to significant differences in long-term trading results.
One-Click FX Traininglets you freely change spreads, so you can practice with various values and
experience how much the spread affects outcomes
and learn.
Besides trading methods, this will be very informative when considering broker selection.
