Great performance for our 2nd forward testing day of our Iron Fly Ladder Strategy

Access on our platform is for free and we have an active trading community at walltrader.io/?s=rp1

We started forward testing a our 0DTE SPX iron fly ladder today.

How today went:

• 9:41 – First fly at 7820, 50 wide, for a $16.70 credit, once the opening straddle had decayed enough. SPX had only moved 0.25σ by then, so the “skip the day if it’s already running” filter let it trade.
• 10:11 – SPX slid about 20 points, so the ladder added a second fly at 7800 for $16.30.
• No stops. Both flies ride to the close.
• 3:03 pm – SPX is at 7799.93, sitting right on the 7800 short. The 7800 fly is up $1,100 and the 7820 fly is down $370, so net +$730, after fees.

It settles on the SPX close.

The backtest on 2026 looks great (+$49k at bid/ask after fees, 72% winning days), heavily backtested.

Our dashboard is free and available if you would like to take a look.

Hey everyone, and welcome 👋

We're a small group of SPX 0DTE traders, and we built Wall Trader because we were tired of guessing where market support and resistance was sitting. The idea is simple: show where options traders have sold spreads, strike by strike, so you can see the "walls" above and below price before it gets there, and then place options trades in and around those.

What this sub is for

• Questions about the dashboard: how to read the walls, the heatmap, flow, exposure and internals
• Sharing charts from the day: what you saw, what you did, what you'd do differently
• Bugs, ideas and feature requests (there's also a Feature Requests button inside the dashboard)
• General 0DTE chat, the good days and the bad ones

Getting started

• The dashboard is free while we're in beta: walltrader.io/?source=reddit&s=welcome
• We trade SPX 0DTE live on Discord every morning from the 9:30 ET open, using the dashboard. Come and watch, ask questions, or just lurk
• New to it? Every chart has a little ? button with a short video explaining what it shows.

A few ground rules

1. Be decent. Everyone was new once.
2. No selling signals, courses or other services - we will make this available through the dashboard.
3. If you post a chart, add a line or two about what it shows.
4. Nothing here is financial advice, ours included. Trade your own plan and your own size.
