P2 Badge Reject invalid oracle address at deployment

The constructor accepts _oracle without validation, so a misconfigured deployment (e.g., address(0) or a non-aggregator address) will leave the contract unable to return a signal because latestRoundData() cannot be decoded as expected. Failing fast in the constructor with an address/code check prevents shipping a permanently broken consumer.

owner = msg.sender;
}

function getSignal() public view returns (string memory) {
(, int256 answer, , , ) = oracle.latestRoundData();
return answer == 1 ? "LONG" : "SHORT";

P1 Badge Validate oracle answers instead of defaulting to SHORT

getSignal() maps every non-1 response to "SHORT", so any unexpected oracle value (for example 0, 2, or a temporary bad payload) is treated as an active short signal. In contexts where autoTrade() will execute positions, this can flip strategy decisions on invalid data rather than failing safely; handle only explicitly supported encodings and revert/hold for anything else.

}

function autoTrade() external {
require(msg.sender == owner, "Only owner");

string memory sig = getSignal();
sig;
// TODO: Integrate DEX execution logic based on signal.
}
