two bits of code with different results - why?

[ShruggedAtlas]

I have rewritten the same entry code in two different ways expecting the entries to be identical but the backtest results are different. Can anyone suggest why this might be?

First entry code:

            if (ToTime(Time[0]) > start && ToTime(Time[0]) < (start + end))
            {                    
                if(direction == "down")
                {                    
                    if(Stochastics(BarsArray[0],3,5,3).K[0] > 80)
                    {    
                        EnterShort(shares, "E1");
                    }
                }
            }
            if (ToTime(Time[0]) > start && ToTime(Time[0]) < (start + end))
            {        
                if(direction == "up")
                {                    
                    if(Stochastics(BarsArray[0],3,5,3).K[0] < 20)
                    {    
                        EnterLong(shares,"E1");
                    }
                }
            }

Second entry code:

            if (ToTime(Time[0]) > start && ToTime(Time[0]) < (start + end))
            {
                //if(Position.MarketPosition == MarketPosition.Flat)
                //{
                    if(direction == "down")
                    {    
                        if(Stochastics(BarsArray[0],3,5,3).K[0] > 80)
                        {    
                            EnterShort(shares, "E1");
                        }
                    }
                    else if(direction == "up")
                    {                    
                        if(Stochastics(BarsArray[0],3,5,3).K[0] < 20)
                        {    
                            EnterLong(shares,"E1");
                        }
                    }                    
                    
                //}
            }

Hello,

Thank you for the question.

It looks like logically these look similar but I do see these are different.

In the first case you are executing One and then the Other, the second sample you are executing One or the Other

The change is with your if statement for direction, the second sample demonstrates the use of else which means that only 1 of these conditions can happen. In the first example you are not using an else which means both could potentially be executed.

I look forward to being of further assistance.

Brilliant! I never would have figured that out. Thanks a lot!!!
