variables.h has them defined as the same thing
Code:
#define TradeResult		g->tr->fResult
#define TradeProfit		g->tr->fResult

Then, what is ->fProfit for?
Code:
typedef struct TRADE {
  ...
  float fResult;		// current profit of the trade
  float fProfit;		// simulated profit
  ...
}

In http://zorro-trader.com/manual/en/trade.htm
TradeProfit is listed, TradeResult is not
However, TradeResult is used in the first example
Also in http://zorro-trader.com/manual/en/buylong.htm Example 3
And two places in http://zorro-trader.com/manual/en/tips.htm
maybe more
