## Deployment consideration

### Order size
A small order size at the beginning is necessary to mitigate operational risks. This is also what JSG is doing.
We will start the deployment with very low trade size. On uniswap v3 is possible to do an arbitrarely small size. The gas fees (on Base) are very low as well (https://basescan.org/chart/gasprice)
When you submit an order on Uniswap your total size in usd is partly eroded by pool fees and gas fees that have total cost
`total_cost_usd = gas_fee_usd + pool_fee * order_value_usd` and your net profit is `net_profit = order_value_usd - total_cost_usd `. Applying the constraint of `net_profit = min_profitability * order_value_usd`, with `pool_fee = 3%`, `gas_fee_usd = 0.004 USD` and `min_profitability = 1%` you get `order_value_usd = 0.00417 USD` as a minimum baseline

### Trade frequency
At most one trade every 30s, this frequency is copied from JSG deployment rules of thumb.
