Algorithm to calculate stoch?

    I am puzzled by how to calculate stochastic. This is the psuedocode I have:

    stoch_fastK(list):
    ````{_, _, _, todaysClose} = list.first()
    ````low = min(list)
    ````high = max(list)
    ````((todayClose - low) / (high - low)) * 100

    stoch(list, period, d, k):
    ````smoothK = for 1..k, 0, fun(kIteration, acc)
    ````````acc + stoch_fastK( sublist(list, kIteration, period)
    ````smoothK / k

    stoch(last_20_datapoints_reverse_order, 14, 7, 2)

    last_20_datapoints_reverse_order, means that the first member is todays close, the next is yesterdays, etc.

    And my results are different from trading view. I am only looking at the smooth K line.

    Can anyone help me complete this?

    Ah I think I see atleast one mistake. The smooth K is over the period length. So to have a smooth k of 2 I need at least 14x2 datapoints, 20 is not enough?

    So take the first 14 points calculate fast K, take the next 14 points, calculate fast K. Add both and / 2?
