You should not change these parameters except "Allow live trading". Disabling this parameter you will get only notifications when provider's accound was changed, but no trade positions will be opened.

SourceDir - root folder of the Meta Trader 4 terminal connected to your account. (equal to the DestinationDir in the Signal provider expert).

PriceDifferencePips - open trade position if price difference between signal price and current price (defined in points) is no more than selected. (For example if your terminal was disconnected and during this time price went far away).

ExpirationHours - open trade position if time difference between signal time and current time is no more than selected value in hours. (For example if your terminal was disconnected for a while).

NumberOfTries - number of consecutive tries to execute trading signal. Sometimes you can get requote or server does not respond. Then expert will try to execute trading signal defined number of times.

LotSize - you can define fixed lot size that will be used in every trade. This parameter works only when VariousLot = false.

VariousLot - this parameter defines lot size. If VariousLot = true then will be used signal provider lot x LotMultiplier. If VariousLot = false then will be used lot = LotSize.

TimeDelaySec - defines time delay between checking for changes in orders (in seconds). If this parameter = 0 (default) then software works as usual and checks for changes on every tick (price change in terminal). This can cause big delays if price changes rarely, but this is how experts should work in MetaTrader. In opposite if you set this parameter to 1 or more seconds - you will get really fast copying of orders even if price did not change during this time. But this in not documented feature in MetaTrader and this causes situation when you can not open expert properties dialog after some time. Though you can fix this problem by changing timeframe on that windows where expert works.

ManualOpenOrders - this feature is useful when you want to open order by better price than on the copied account. If this parameter = "true" you will get only notification and should open this order manually when you want to do this. To allow system to track this order and make automaticall changes (and close it after all) you should put the order ticket number from the copied account to "Comments" field of this order.
