You should not modify these options. They must be exactly as in the image.

DestinationDir - root folder of the Meta Trader 4 terminal connected to your account.

LotMultiplier - lot that signal provider opened on his account will be multiplied on this value. It allows you to decrease or increase resulting lot to suit your requirements to your account.

EventSound - play this sound when some changes happen on the copied account. Sound files should be placed to "<MetaTrader>\Sounds\" folder. Sound files should have *.wav format.

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.

Examples how to apply LotMultiplier:

Example 1: Signal provider trades on account 1.000, your account is 50.000, if you copy signal provider's trades as is you will get too small profit (loss). So you can set multiplier 50, and when signal provider opened position with lot 0.1 you will get position with lot 5.

Example 2: Signal provider trader on account 100.000, your account is 20.000. It will be dangerous to your account to open the same lot, sometimes it will be impossible. So you can set multiplier 0.2 and when signal provider opened position with low 10 you will get position with lot 2. If resulting lot is smaller then minimum lot in your MetaTrader then it will be used minimum lot.
