Publishing the walk-forward checklist I refuse to skip: - IS/OOS window lengths written down before seeing results - Anchored vs rolling chosen on purpose - Parameter stability…
Trying to map the [QuantMogul](https://quantmogul.ai) surface honestly for a retail workflow: - Web: research / agentic / marketplace-ish views - Desktop: walk-forward, Monte…
I ran two EAs live (small size) and re-backtested the identical period every month, logging the divergence. Six months of data: **EA-A (EURUSD H1 trend):** backtest PF 1.61, live…
NFP, FOMC, CPI — do you pause the EA, reduce size, or let it run? I've seen all three preached with total confidence. What does the data say in *your* trading? If you logged it,…
Ran 5 years of backtests, 99% modelling quality, profit factor 2.1, realistic spread, slippage modelled. Live result: -40% in 11 weeks. What did I miss? Genuinely asking — I want…
On Walk-forward analysis checklist I actually use before trusting an EA 1 month ago
Add: write the rejection criteria before you open the report. If you negotiate with the chart after seeing OOS, you already overfit your process.
On Portfolio Doctor by Zoe — useful portfolio rescue tool or just a fancy dashboard? 1 month ago
Used Portfolio Doctor by Zoe on a 12-position mess. The useful part was not the letter-grade — it was the recovery-tree forcing me to write down "if USD spikes, which three legs die together?". Cons: OCR of my broker screenshot misread one lot size, and the narrative tone can…
On Agentic Trading on QuantMogul — mandate playbooks vs classic EA farms 1 month ago
I still gate every sleeve through forward survival thinking — WorldBotRank as one input, my own demo log as the real one. Agentic is orchestration sugar; risk ownership is not optional.
On EA Farm / FarmBot style portfolios — how do you diversify without correlation blow-ups? 1 month ago
Daily PnL correlation matrix in a spreadsheet first. Anything >0.6 over 60 trading days shares a risk budget. My EA Farm is handy for seeing what is running; QuantMogul MC is where I decide if the farm's joint drawdown is survivable.…
On Walk-forward results for a simple EURUSD trend EA, warts and all 1 month ago
The 30% in-sample to out-of-sample haircut matches my rule of thumb — I assume 25-40% degradation and I am pleasantly surprised maybe once a year. And thank you for the honest "not fundable, it is a building block" framing. That sentence is what most WFO posts carefully omit.
On Autopsy: what the 2025 chop did to my 4-strategy portfolio 1 month ago
Flat is a win in a transition year — most single-strategy accounts I track were down 20-40%. What was the return correlation between your trend and mean-reversion sleeves? My similar pair ran about -0.3 in 2025, which is the only reason my year looked like yours.
On forward test บนบัญชี demo ยังไงให้เชื่อผลได้ ต้องเก็บตัวเลขอะไรบ้าง 1 month ago
My logging list (English, hope that's ok). Per trade: requested vs filled price, spread at entry, duration, and P&L vs the same-period backtest trade. Weekly: live equity curve plotted against the backtest's percentile band. Pass criteria I actually use: live PF within 20% of backtest PF, average…
On I logged 30 days of slippage on 3 brokers — results inside 1 month ago
The asymmetry is the tell. Symmetric slippage is honest market impact; consistently asymmetric slippage is the broker's business model. Question: did B's asymmetry persist after you excluded the news windows? That separates "worse during chaos" from "worse by design".
On PortfolioVerse 470 AI funds — idea mine or randomness leaderboard? 1 month ago
Same rule on PortfolioVerse: process theft only. I rewrite the idea in my own words, WFO it in QuantMogul, then demo. If I cannot explain the edge without the leaderboard rank, I discard it.
On Six months of backtest-vs-live divergence logging on 2 EAs — exact numbers 1 month ago
Monotonic vs jump is exactly the right framing — mine were both, one per EA, and I never separated them until now. Adding divergence-shape tracking to the monthly log. This thread is why I post data here.
