struct method not working
struct method not working

Hi,
First of all, I only tested this on backtesting since we are saturday.
I created a List<TickData> named tickRecord, which stores the following struct :
public struct TickData
{
public double Variation;
public void SetVariation(double _newPrice, double _oldPrice)
{
if (_newPrice > _oldPrice)
Variation = _newPrice - _oldPrice;
else if (_newPrice < _oldPrice)
Variation = -(_oldPrice - _newPrice);
else
Variation = 0;
}
}
When I try to set the Variation property through a for loop like this :
for (int i = tickRecord.Count - 1; i >= 0; i--)
{
if (i = 0)
// Do nothing
else
tickRecord[i].SetVariation(tickRecord[i].Bid, tickRecord[i - 1].Bid);
}
It doesn't work, Variation stays the same :
for i = 1 : 1,12879 - 1,12879 = 0
for i = 2 : 1,12879 - 1,12879 = 0
for i = 3 : 1,1288 - 1,12879 = 0
for i = 4 : 1,12879 - 1,1288 = 0
for i = 5 : 1,1288 - 1,12879 = 0
etc...
From my research I'd say, tickRecord[i].SetVariation(); is the problem.
But I can't find anywhere how to make it work or why does it do that.

I solved the problem by making a class instead of a struct

I tried to do it outside of the loop like this :
bool isFirstTick = true; TickData currentData; currentData.Time = Server.Time; currentData.Ask = Symbol.Ask; currentData.Bid = Symbol.Bid; currentData.Variation = 0; if (isFirstTick) { currentData.SetVariation(0, 0); isFirstTick = false; } else currentData.SetVariation(currentData.Bid, tickRecord[tickRecord.Count - 1].Bid); tickRecord.Add(currentData);It still didn't work, same results...
