{% hint style="info" %}
**Note**: when doing any execute that is not <mark style="color:red;">`place_orders`</mark>, i.e. <mark style="color:red;">`withdraw_collateral`</mark>, <mark style="color:red;">`liquidate_subaccount`</mark>, you want to use <mark style="color:red;">`tx_nonce`</mark> as the nonce. <mark style="color:red;">`tx_nonce`</mark> increments by one each time a successful execute goes through. <mark style="color:red;">`order_nonce`</mark> is a historical artifact for the frontend, and simply returns the current timestamp in milliseconds plus 100000 multiplied by 2\*\*20.
