What this shows
For each Entry 1 signal, how far did price move against you (MAE) and how far did it move for you (MFE) — as % of entry price. This is underlying price movement only, not options P&L.
• Green on scatter = MFE exceeded the pain · Red = pain exceeded the gain
No slippage modeled. Treat as best-case estimates.

Entry Burn — MAE After Signal
Every dot is one trade. The Y-axis is how far the underlying moved against your position after you entered, measured as a percent of entry price. Green dots are trades where price barely moved against you (under 0.15%) — the entry was clean and you didn't have to sit through much pain. Orange dots moved against you between 0.15% and 0.50% before reversing. Red dots punished you hard, over 0.50% adverse before anything else happened. The connecting line shows the sequence over time. This plot answers: how often does the entry hurt you, and by how much?
Air Before Pain — Breath Ratio
This plot only includes trades where there was adverse movement (MAE > 0). For each of those trades, it asks: before price turned against you, how much did it move in your favor first? The ratio is that favorable move divided by the adverse move. A ratio above 1.0 (green) means you got more air than pain — price went your way before it came back. A ratio between 0 and 1 (orange) means you got some breathing room but the pain was bigger than the float. A ratio of exactly 0 (red) means price went straight against you the moment you entered — no float at all, instant burn. Ratios are capped at 5.00 for readability; hover a dot to see the true value. This plot answers: when the entry goes against you, did it give you something first — or did it just burn you immediately?
Together: Entry Burn tells you the size of the risk. Breath Ratio tells you the order — did the trade respect the entry before punishing it. A ticker with low MAE and high Breath Ratio is an ideal entry pattern.
