TakeProfit order

I would like to use the order type:   

PlaceLimitOrder(TradeType.Buy, Symbol, Volume, Price, "myLabel", StopLoss, TakeProfit);

1)  The smallest value that can be used for TakeProfit is 1 pip which for some currency pairs is quite high.  I would like to take profits earlier.  How can I take profits at less than 1 pip?

2)  Is there a way to automatically detect if the TakeProfit has executed and then automatically start another order?
