Tribonacci_RF攻略#3: How to choose a suitable time window and currency pairs (spread measures / for beginners)
It is a black cat.
In the previous article (Tribonacci_RF Strategy #2), I organized the concepts of trailing take profit (8 pips start / 1 pip increments) and cautions regarding stop levels and spreads.
This time, as a continuation, I will summarize for beginners which timeframes and currency pairs minimize the chance of accidents.
Putting it bluntly, this EA trails very finely (in 1-pip steps), so
the more you run it during times of spread volatility, the more the entry, take profit growth, and losses will become erratic.
1) Why results change with time of day
This EA enters after waiting for a pullback, but actual execution is affected by spreads and slippage.
In particular, because trailing follows closely,
・Wide spreads → profits can be shaved off even when in profit
・More price reversals → trailing gets tossed around
・Surges from economic indicators → volatility can become unpredictable
…that is the structure.
2) Typical patterns where spreads loosen up (3 patterns)
Don’t overthink this; it’s generally these three.
Pattern ①: Thin order book times
When fewer participants trade, spreads tend to widen and order execution becomes choppier.
Pattern ②: Economic data releases / sudden moves
Sharp expansions plus slippage occur, and results vary even when aiming for pullbacks/returns.
Pattern ③: Start of the week / end of the week
Price moves can differ from usual, making the experience unstable.
3) For beginners: the simplest operating rule
Before deciding to stop, start with just this.
Rule: Run during times when spreads are most stable
This alone changes how volatile it is
The stopping decision is less of a hurdle, making it easier to continue
4) Practice: Steps to determine your own “operating window”
Because spreads vary by broker and account type, deciding based on your own environment is the strongest approach.
・Limit to 1–2 currency pairs you want to trade
・Observe the spreads during your desired times (for a few days is fine)
・Make the time with stable spreads your “operating window”
・On days with obvious data-release-like volatility, avoid trading (build a habit)
5) How to choose currency pairs (3 axes)
For currency pairs, keep to these three axes.
・Spread stability (not just narrow, but stable without fluctuations)
・Range tendency (pullbacks/returns tend to form)
・Risk of abrupt changes (frequency of large one-way moves)
Beginners should start with major pairs that have stable spreads (M15). (Note: starting with minor currencies with wide spreads can cause more instability due to the EA’s nature.)
6) Summary
This EA has very fine trailing, so it is heavily affected by spreads
Therefore, simply choosing the time to run can lead to stability
First, create an operating window where spreads are stable
Choose currency pairs by combining spread stability, range tendency, and abrupt-change risk
