Fragmented orders make it more difficult for others to anticipate future trades by:

1. Concealing order size: Breaking up orders into smaller pieces makes it harder to determine the total size of the trade, making it difficult to anticipate the trader's future actions.

2. Disguising trading patterns: Fragmented orders can disguise a trader's typical trading patterns, such as their entry and exit points, making it harder for others to anticipate their next move.

3. Reducing transparency: By spreading orders across multiple exchanges, brokers, or trading platforms, fragmented orders reduce transparency and make it harder for others to gather intelligence on a trader's future trading intentions.

4. Increasing uncertainty: Fragmented orders introduce uncertainty, making it harder for others to confidently anticipate a trader's future trades, and reducing the likelihood of others trading ahead of them.

By reducing the visibility of future trading intentions, fragmented orders help traders maintain a competitive edge and protect their trading strategies from being reverse-engineered or disrupted by others.
