How to compare with previous or next element's properties in List<T> while the compare fields are dynamic?

I have a class

class MarketData
{
    public double Open {get;set;}
    public double High{get;set;}
    public double Low{get;set;}
    public double Close{get;set;}
}

Now I have created List and filled it with last 30 days data. Here's where I am struggling to find best solution for this. A user can enter conditions manually but in fixed format, the fields can be e.g

Open is Greater Than Previous.Close

High is Less Than Previous.Low

Low is Greater Than Next.High,etc

I am parsing the string conditions to

public enum ConditionComparer { And, Or }

class SimpleCondition
{
    public string Operand1 { get; set; }
    public Operators Operator { get; set; }
    public string Operand2 { get; set; }
    public ConditionComparer Compare { get; set; }
}

Now I have to apply this conditions on the List<MarketData> and get matching results.

I used DynamicQueryable class in bit different scenario where conditions where dynamic and it worked perfectly but now I have to compare record with next or previous record.
