TickerAll: Stop-limit orders (buy & sell stop-limit)

TickerAll currently supports market, limit, and stop orders — but not stop-limit orders. Please add support for buy stop-limit and sell stop-limit order types. A stop-limit order combines a stop trigger with a limit price: when the market reaches the stop price, a limit order at the specified limit price is placed. This gives control over the fill price that a plain stop order (which fills at market once triggered) does not offer. This completes the standard pending-order set: limit, stop, and stop-limit.
