Kosta Ouzas argues position sizing, not entry timing, determines whether a trading bot survives. It controls how much downside the bot absorbs and where liquidation happens relative to market moves. Identical strategies fail or succeed depending on position size alone.
The part of the system that keeps you alive isn't the entry. It's actually the size. So position sizing is the mechanism that determines how deep you can go into a safety range, how much downside that your bot and your algorithm can absorb, and where your liquidation level sits relative to reality. This is the difference between a system that can withstand volatility and one that simply collapses the moment conditions change.
