TRADE : "on signal day" - backtest

[horacio]

what changes in the backtest whether or not we check the option "trade:   on signal day"  ?

[Sacha]

Normally when signal occurs the trade can only happen on next candle (or day for Eod chart). But if you think you can manage to trade on the same candle on which signal occurs then you can check this. Otherwise backtesting will trade on next candle.

Please let me know if you still need clarification.
