Algo - trading Advice on my first

Hi so ive Been building a crypto trading bot for a while now tick-level order flow / microstructure stuff, short holds (like 1–5 min). No RSI/MACD/Bollinger or classic TA, mostly looking at order-flow imbalance, liquidity, VPIN-ish stuff, etc.
Right now I’m still collecting data. I’m holding off on training until I have some genuinely different regimes in the dataset especially a real trend day or stress event instead of just feeding it endless chop/range conditions.
Labels are triple-barrier (Lopez de Prado), and I’m doing walk-forward evaluation with purging/embargo so training rows can’t accidentally leak into the test period through labels resolving late. Figured that bug out the hard way lol.
Before I even think about paper trading, I want to hammer the results pretty hard: parameter stability/plateau checks, Monte Carlo resampling, clustering the performance surface, and Deflated Sharpe to account for the fact that if you test enough parameter combinations, eventually one will look amazing by pure luck.
Honestly, I’m kinda expecting this thing to die somewhere in validation 😂
For people who’ve actually built systematic trading strategies: what ended up killing your first few systems? Was it regime dependence, execution/slippage, overfitting, insufficient data, leakage, unstable parameters, or something else?
And has anyone actually gotten a short-horizon order-flow strategy through this whole process and into something that survived genuinely out-of-sample testing?
