擬似コードの理解

Hi everybody. I have some troubles understanding Pseudo code. Could somebody please help?

What is:

   1. Close(1), Open(7) – this is an average on n days? Or is it a value n days behind today?

   2.  “Something Crosses Something”. 

               Example: Close(8) Crosses Below Ichimoku(9, 26, 52, Tenkan-sen)

        The term “crosses below” means that first line crosses second line down, right?

   3. What is “Something Closes below Something.” Here it Closes, not Crosses, I have no idea what could it be…

               Example: Close(4) Closes Below ParabolicSAR(0.02, 0.2))

   4. LowestInRange(17, 0, 18, 0) – there are four parameters, what do they mean? Also it is applied to which price? To close or to high?

Also sometimes I get things like “true and Condition”, which is redundant. Would it be possible to add a check in order to avoid such things in the future?

こんにちは,

1. Close(1) means close 1 bar ago

  Open(7) means open 7 bars ago

2. something crosses something – as you say, it means first line crosses the second one

3. something closes below something – this is usually used with price data

Close(4) Closes Below ParabolicSAR(0.02, 0.2)). It means that the bar 4 bars ago closed below parabolic SAR.

It doesn’t need to cross the indicator, it only needs to close below it.

4. LowestInRange(HourFrom, MinuteFrom, HourTo, MinuteTo) – it returns the lowest low during given time range

5. Also sometimes I get things like “true and Condition”, which is redundant. Would it be possible to add a check in order to avoid such things in the future?

ok, I’ll look at this, it should be filtered out
