### Notes on Batch Ordering:

#### Speed Bump (Latency Protection)

Batch orders are subject to a conditional randomized 50-100ms delay to protect liquidity providers from adverse selection:\
\
Speed bump is applied if the batch contains:

* Market orders (CreateMarket)
* Limit orders with TIF = GTC or IOC

Speed bump is NOT applied if the batch only contains:

* Add Liquidity Only orders (TIF = ALO)
* Top of Book orders (TIF = TOB)
* Cancel operations
* TP/SL operations

#### Signature Requirements

* Each action in the batch must be individually signed
* All signatures must be valid for the batch to process

#### Execution Behavior and Limits

* Maximum 10 actions per batch request
* Actions are executed atomically in the order provided
* If one action fails, subsequent actions are still attempted
