Entry Signal
The condition that opens a position — the moment a strategy commits money to an opinion.
What it means
An entry signal is a boolean: at this second, for this symbol, do the conditions hold? Good entries are usually a stack of cheap filters — liquidity, session time, trend, trigger — each removing a class of bad trades the others miss.
The uncomfortable truth of systematic trading is that entries matter less than people think and exits more; but entries decide your opportunity set, and an entry that fires in untradeable conditions (wide spreads, halts, no liquidity) loses money before the exit logic ever runs.
Why traders care
- Stacked filters beat one clever condition for robustness.
- Every entry should carry its own tradeability guards, not assume them.
In a TraderWe strategy
매수 = Price > Sma(60) and Strength > 120 and (Ask1 - Bid1) / Price < 0.003
if 매수:
Buy()Trend, tape control, and a spread guard — then commit. Assigning 매수 alone does not order; Buy() does.
