Suppose I am using tradestation 1--for buy stop orders say current price is 100, I want to place a buy stop order at 110. Is this buy stop order monitored by tradestation on my own PC or sent to the broker's server and monitored there ? 2--for trailing stop orders say I want to sell 10 points below the highest price after I enter a long position. So for everytime the market moves higher, my sell trigger price will be updated, is this updation monitor by tradestation on my own PC or sent to the broker's server and monitored (and sell stop orders updated ) there ? 3--regard 1,2 ,same answers for other automation programs ?(other than tradesation )
