Listen to our Trading Strategy Podcast episode #16 with Stratwise (@StratwiseAI) and learn why a strategy built to survive first and earn second can turn market volatility into income without leverage.
In this episode, Nertila (@theblue_panda) from Trading Strategy discusses with Iaroslav (@Yava_web3) from Stratwise. Stratwise is an AI-driven crypto asset manager that runs non-custodial, spot-only strategies, including public vaults on Hyperliquid, using a machine-learning engine to trade volatility.

Pretraining provides useful, reusable structure, while source selection and adaptation determine how effectively that structure transfers to a target task. So, to answer your question: yes, pretrained time-series foundation models are useful forecasting tools and can outperform models trained on a single asset, but their advantage depends strongly on the relationship between the pretraining and target distributions. Our next study will investigate how proximity in probability space affects transfer performance, with potentially far-reaching implications for how pretraining datasets should be constructed.
So where is the martingale in our own research?
After two explainers on martingales in financial AI, a fair question: where is it in our work?
As a certificate. A supermartingale envelope bounds a crypto price over a whole holding window. That lets us size the collateral a spotโperpetual hedge needs before opening it - including the awkward moment when funding has been paid but the collateral transfer hasn't arrived yet.
As a loss. One condition, inverse wealth must be a supermartingale, plugs into Linear, MLP, GRU and Transformer policies and keeps wealth away from a capital floor
Enforced exactly under a known law, the condition becomes a guarantee; used only as a training penalty, it improves risk but does not guarantee it. We show where it helps - and, just as carefully, where it doesn't.
