- upgraded code
- using the new set of prices (the 33 types of prices)
- some minor changes made

So, what you are asking is not possible since the DMI would be approximated to some other value and it would show something actually not related to real prices at all

If indicators, which are based on close price value, could forward calculation predict a zero/cross point. I don't have much knowledge in this field. I am not specifically talking about DMI as I only assume it is calculated using Close price values.
For instance
DMI cross over point should be able to be predicted if we know how much the price needs to return for crossover to occur, then this can be plotted on chart.
Changing the close price to find crossover then plotting it on chart.

I assume only indicators based solely on close value should be able to be predicted, but your more knowledgeable.
If possible what can this be applied to and how can we expand it?

To calculate +DI and −DI, one needs price data consisting of high, low, and closing prices each period (typically each day). One first calculates the directional movement (+DM and −DM):

    UpMove = today's high − yesterday's high
    DownMove = yesterday's low − today's low
    if UpMove > DownMove and UpMove > 0, then +DM = UpMove, else +DM = 0
    if DownMove > UpMove and DownMove > 0, then −DM = DownMove, else −DM = 0

After selecting the number of periods (Wilder used 14 days originally), +DI and −DI are:

    +DI = 100 times the smoothed moving average of (+DM) divided by average true range
    −DI = 100 times the smoothed moving average of (−DM) divided by average true range

The smoothed moving average is calculated over the number of periods selected, and the average true range is a smoothed average of the true ranges. Then:

    A.D.X. = 100 times the smoothed moving average of the absolute value of (+DI − −DI) divided by (+DI + −DI)

Variations of this calculation typically involve using different types of moving averages, such as an exponential moving average, a weighted moving average or an adaptive moving average.

Please check how that could fit in your idea

Above is based on the same request i did sometime ago. The logic was to: "Calculate the Eventual price THAT could MEET a Specific CRITERIA". My request was based on a Simple Moving Average. In Technical Analysis the Cross of a Moving Average and the Prices, is giving a Signal to Open or Close a Position. Suppose we use a Simple MA, it would be helpful if we could know the crossing point with Prices .... As it is not possible to Predict-Calculate such Price, we can try to calculate it by "making an hypothesis" by imposing following question ... What should be the Close Price of the actual Bar in order to make the MA and Prices to Cross ??? .... The result of such calculation can be used for different purposes, like Take Profit, Stop Loss, Close Position and Open Position ... Using this logic, many similar calculations could be made, like the idea of Sanni123 ... Unfortunately i do not have coding knowledge in order to realize such indicator-calculation ...
Thank you for your attention.
Best Regards
Dimitri

Try it out (the "prediction" calculation as it is calculated in this example is possible only for SMA - other averages types would have completely different "prediction" calculation). The dotted line is the actual SMA, and the "blue" line is the required price that would cause crossing of the SMA and the price

I have really to Thank YOU so much for your immense supporting all of us ...
I notice that the graphic impression i have from the result, is not compatible with what i was optically expecting. As i already told you, i have no coding knowledge, but i can express mathematically my thinking ... Point 1.: I Agree that simple MA is the non complicate of other MA's. Point 2.: It is really great the possibility to use all those prices you have included. Point 3.: i will try to give you an example of the calculation : Suppose we use a Simple MA of Close Price for the last 5 Periods without counting the active non closed bar. The calculation for the Simple 5 periods MA is : Last Closed Bar which we give the name Close_1, the previous of that is Close_2 ... up to Close_5. We add Close_1+Close_2+Close_3+Close_4+Close_5 and we divide the sum by 5. This should be the MA price. Now as we want to "calculate-predict" what should be the price in order to "cross the MA with Prices", we assume that MA=Price, or (X+Close_1+Close_2+Close_3+Close_4)/5= X (where X should be the "predicted Closing Price of the ACTIVE Bar") ... Please just confirm calculation. Thank you Thank you Thank you ....
Best Regards
Dimitri
