simd tx broadcast tx-signed.json --chain-id my-test-chain --gas auto --fees 250stake

The tx broadcast command does not read the --fees or the --gas flags, because it is not possible to change the gas or the fees for a signed transaction. As a result, these flags shouldn't be mentioned in the example.
