Visualize probable outcomes using branching decision trees to model strategy behavior and master your mental game.
A strategy isn't just a win or loss — it's a branching tree of possibilities. Learn to model them and master your mental game.
You might know your:
But what does that look like in real time?
That’s where Trade Expectancy Trees come in.
They show you:
A tree diagram that maps the possible outcomes of a trade or a series of trades — based on win/loss probabilities and outcome sizes (R).
Instead of just saying:
“My EV is +0.5R”
You see:
You’re now trading with eyes open — aware of variance, not shocked by it.
Your stats:
Trade 1 Tree:
┌── Win (45%) → +2R
Start ──┤
└── Loss (55%) → –1R
EV = (0.45 × 2) + (0.55 × –1) = +0.35R
Already profitable — but only over many trades.
Now expand it to 2 trades:
┌─ Win ─ Win → +4R
│
┌───┤
│ └─ Win ─ Loss → +1R
Start│
│ ┌─ Loss ─ Win → +1R
└───┤
└─ Loss ─ Loss → –2R
Outcome Probabilities:
Insight:
Even with a strong edge, nearly 1 in 3 sequences will be a back-to-back loss.
That’s why emotional resilience and sample size matter.
You can’t draw it by hand anymore — but you can:
This gives you:
You won’t panic after 3 losses if your tree shows it’s a common outcome on the path to +10R.
You stop evaluating single trades emotionally. You zoom out and ask:
“Am I executing my system over 50+ trades?”
You can build risk tiers, drawdown thresholds, and capital scaling plans based on:
Optional: Simulate in Excel or Python to model 1000+ sequences.
Most traders blow up not from bad systems — but from being surprised by normal randomness.
Trade expectancy trees give you vision.
Know what paths are possible. Know what paths are likely. And keep executing until the math catches up.
