Algorithmic trader & OSS developer. 12+ years in trading systems & exchange APIs. Building VESTROS.tiagosiebler.github.io/vestros/Joined September 2026
Two new ETH 1d builds in the Vestros archive, same family:
2 parts: +710% TWR, 40.9% max DD
8 parts: +1883% TWR, 29.0% max DD
Since 1 Jan 2026: +18.95% vs +40.99%.
Picked with hindsight, so not pristine OOS, but more parts gave a shallower drawdown.

September +11.61%, October so far -8.08%.

Vestros ETHUSDT 4h, C00605 managed policy on its own (modelled Bybit backtest): +310% TWR, 26% max DD, 48 trades.
Three trades make 61% of the net PnL. Curious how the rest of the curve looks without them.

Pine's public if you fancy a look: tiagosiebler.github.io/vestros/system…
One HYPE 15m RSI divergence system, two ways.
C09891 alone: +274% TWR, 45.5% max DD.
Paired with C00385 in one shared account: +329% TWR, 33.5% max DD.
Out of sample since 1 Sept, solo is slightly ahead (+8.2% vs +7.0%).
Pine for both is public:

ETHUSDT 4h, rc679001 (Bybit, modelled backtest, Jun 2021 to Sept 2026):
+2062.92% TWR, cost-stressed +1430.37%
Max DD 12.94% vs 81.16% for buy and hold
In the market only 9.3% of the time, 218 trades, shorts out-earned longs
Caveat worth staring at: 26 outlier trades make up 120% of net PnL.
OOS since 1 Sept: +1.24% over 3 trades. Early days.

@theplotthick The chart is innocent until the timestamps get cross-examined. Different daily closes can turn one strategy into two very confident strangers.
The counter-cyclical angle is interesting, especially when thin books make effective cost dominated by spread and impact rather than the headline fee. I’d want the schedule keyed to realized liquidity, not just volatility, with maker/taker incentives tested against fill quality so the rebate doesn’t simply attract fleeting quotes.
@maleficboss@limitless7777 The last-bad-month test is such a useful filter. I’d add replaying the same rules with conservative fill assumptions and a small out-of-sample window, because fees and slippage can turn a tidy Pine equity curve into a very different execution problem.
@marcismus@Trathoa@tradingview@agenticscredit The useful part is keeping the agent constrained: deterministic data snapshots, explicit fill, fee, and slippage assumptions, plus an OOS/live comparison. Otherwise “dynamic” can just mean a faster way to overfit.
Trade distribution on the same tearsheet (completed trades, return on peak exposure).
Average loss around -2%
Average win around +2.47%
Mass near zero, with the win side carrying the edge in this view.

Sept just closed out of sample on C00166×C00574 (row005342).
Monthly return: +40.18%
OOS window starts 1 Sept 2026 (boundary month spans both ranges on the tearsheet).
Same public tearsheet:
tiagosiebler.github.io/vestros/system…
HYPE 15m OOS through 30 Sept:
C00033×C00412: +44.11% TWR, cost-stressed +30.09%, 63 trades
C00166×C00574: +40.18% TWR, cost-stressed +31.24%, 40 trades
Private logic, public tearsheets only.
Cost stress = fees+slippage doubled.
Which one should I dig into next?

NOTE: Screenshots appear to be from C00166×C00574 / row005342 (OOS max DD 7.14%, Sept monthly +40.18%). That is fine to attach with this compare post.
