Know Exactly Where Your Fills Are Costing You.

Day traders live and die by execution. SignalDeck measures it on every single trade.

Entry Slippage

The difference between your intended entry and your actual fill. Identifies whether your market orders are costing you edge at open.

Exit Slippage

How much you're giving back on exit. High exit slippage on winning trades means your actual R is lower than planned.

MAE (Adverse Excursion)

How far a trade moved against you before turning profitable. Reveals whether your stops are too tight or your entries too early.

MFE (Favorable Excursion)

The maximum profit available on each trade before you exited. If MFE consistently exceeds your actual exit, you're leaving R on the table.

Turn Psychology from a
Vague Problem into Data.

Every day trader knows they FOMO into trades. Most can't quantify how much it costs them. Tag each trade with its psychological driver and the journal shows you exactly which behaviors are draining your R over time — and at which times of day they appear most often.

When your FOMO trades average -0.8R and your plan-following trades average +0.6R, the fix is obvious. The data forces the conversation you've been avoiding.

Frequently Asked Questions

What is the best trading journal for day traders?

SignalDeck offers intraday backtesting (5m–4h timeframes), execution quality analysis (entry/exit slippage, MAE/MFE), behavioral tagging, and real-time SQN scoring per strategy. Free during beta.

Does SignalDeck support intraday backtesting?

Yes — 5m, 15m, 30m, 1h, and 4h timeframes. Walk-Forward Analysis and Monte Carlo simulation apply at all timeframes. No other trading journal combines intraday backtesting with Walk-Forward Analysis and Monte Carlo.

What is execution quality analysis?

Entry slippage, exit slippage, limit alpha, and MAE/MFE scatter plots measured per trade, per strategy, and per symbol. Tells you whether your fills are costing you R and where you're leaving money on the table.

How does behavioral tagging work?

Tag each trade with its psychological driver (FOMO, hesitation, revenge trading, plan-following). SignalDeck shows you the average R-multiple per tag so you can quantify exactly what each psychological pattern costs you over time.
