Module stop 

Stop orders: the request of the shared interface to ALOR’s stop and stop-limit orders, and back.

ALOR has two kinds of stop orders, and both keep the trigger price and the condition (more, less, …): a stop order (a market order is made on trigger) and a stop-limit order (a limit order is made, with its own price). The shared interface has three kinds:

Request	ALOR
StopLoss, TakeProfit without limit_price	a stop order. The condition follows the side and the kind (a sell stop-loss triggers when the price falls to the trigger price, a sell take-profit when it rises to it)
StopLoss, TakeProfit with limit_price, StopLimit	a stop-limit order (a StopLimit without limit_price is refused)

A stop order read back has the kind StopLoss or TakeProfit (from the side and the condition) and a stop-limit order has the kind StopLimit: ALOR does not keep which of the two a bot meant.
