**Key Point #2: The 1:0.5 ratio**
{% endhint %}

If, for example, you plan to deploy $100k USD on an FXPool, we recommend having $50k USD of external liquidity elsewhere to ensure that as the FXPool trades towards the end of the beta region, arbitrageurs will have a venue to bring the FXPool back or closer to the 50:50 LP ratio. 

Examples (with FX rates at time of writing):
