Trading Psychology
Trading psychology, measured — not preached.
Most trading psychology content is a book of biases. Useful, but abstract. EI ALGOS reads your trades and shows you which biases are actually costing *you* — with your own data as evidence.
Why it matters
Strategy is table stakes. Behaviour is the edge.
Two traders with identical setups end up in different places because one traded them consistently and the other did not.
Trading psychology is the study of why humans — smart, informed, well-intentioned humans — routinely deviate from their own plans. There are dozens of documented biases. But biases in a book are not the same as biases in your account.
EI ALGOS closes the gap. The Emotion Score reads your recent behaviour and surfaces which patterns are showing up. LIANA cites the trades. You stop guessing about your discipline and start seeing it.
Six biases traders should know
Confirmation bias
Seeing only the evidence that confirms the trade you already want to take.
Loss aversion
Feeling losses roughly twice as hard as equivalent gains — why we cut winners and hold losers.
Overconfidence
Sizing up after a win streak — statistically the moment your edge is most likely to mean-revert.
Revenge trading
Trying to "make it back" after a loss with a bigger, faster, worse-planned trade.
FOMO
Chasing a move that has already run because sitting flat feels worse than being wrong.
Anchoring
Fixating on the entry price as the reference for a decision the market has moved past.
