Add a second trade if market have moved against one for x pips?

Hi,

trying to create a simple cBot with the origins from the sample RSI template.

How can I add the possibility to add a second trade in the same direction as the original trade if the market have moved agains me for x pips with two times the original size?

Current logic:

        protected override void OnTick()
        {
            if (rsi.Result.LastValue < 30)
            {
                Close(TradeType.Sell);
                Open(TradeType.Buy);
            }
            else if (rsi.Result.LastValue > 70)
            {
                Close(TradeType.Buy);
                Open(TradeType.Sell);
            }
        }

Any help appreciated!

Thx!
