adaptive position sizing - regime-based approach
position sizing makes or breaks algo trading. been refining adaptive approach last 6 months. finally working consistently. the problem with static sizing # most algo traders:
regime detection - walk-forward validation improving accuracy
regime detection upgraded. walk-forward validation running. accuracy improving. the problem # static regime parameters: optimized on historical data.
regime detection filtering framework - how i adapt to market conditions
august forcing me to rely on filters. figured worth explaining how regime detection works. learned a lot from options selling regime discussions on NexusFi about adapting to conditions. the problem # strategies don’t work in all conditions.
walk-forward optimization - how i avoid overfitting my strategies
overfitting = #1 way algos fail in production. backtest looks amazing. live trading implodes. walk-forward optimization prevents this. been discussing validation techniques on NexusFi algo trading threads and walk-forward is the gold standard.

polygon.io vs alpha vantage - which data feed for algo trading
data feeds = foundation of algo trading. garbage data = garbage trades. i’ve used both polygon.io and alpha vantage extensively. spent months researching data feeds when i started trading. NexusFi community helped narrow down options to these two.
backtesting overfitting - how i avoid curve-fitting my algos
backtesting is where most algo traders hurt themselves. they optimize parameters until strategy looks perfect on historical data. then go live and it fails immediately. classic overfitting. learned this the hard way. saw countless traders on NexusFi backtesting discussions make same mistake when i joined in 2023.
