Modify an indicator to print arrows on chart correctly

hello, i have an indicator that doesn't show arrows as intended. i would appreciate it if this could be fixed as soon as possible. the issue is explained below.

- the combinar indicator has no problem as it can combine any two indicators and display arrows.

-  the indicator k3 has a problem with is buffer 0.

1: **as shown in the figures below, i want that the combinar to show arrows based on the color of k3.

     that is, when k3 trend color is blue, a blue arrow should be displayed on the current candle and when k3 is

     magenta, a green arrow should display on the current candle. the arrows should display on the current candle based on the color of the k3.

    **k3 has 3 buffers, 0 for blue,1 for magenta and 2 for gold. when  0 and 1 are entered into the combinar indicator, the results are shown as below with blue and green arrows printed on the same candle.

     but i want the arrows to be printed based on the color of k3, i.e blue arrows only when k3 is blue and green arrows only when k3 is magenta.

2: ** As shown in the figures below, further investigation shows buffers 1 and 2 works just fine.

    **That is referring to the figures below, when buffers 1 and 2 are entered into the combinar, the arrows are printed correctly on the chart as shown below.

    **That is the green arrow is printed when k3 is green only  (buffer 1) and the blue arrow is printed when k3 is gold  (buffer 2). This stipulates that the arrows are printed as desired.

3: ** As illustrated in the figures below, investigations show that, buffer 0 of k3 does not print arrows as desired. 

    ** when it's entered into the combinar indicator, blue arrows are printed when k3 color is blue  (buffer 0) and blue arrows are still printed when k3 is magenta  (buffer 1), which should not be the case.

    ** just blue arrows ought to be printed only when k3 is blue.

    ** so this concludes my findings that buffer 0 of k3 must surely be the problem.

N/B: 1):  the calculations of k3 are okay and i want no changes to it, just the display of arrows is the problem.

        2): the  combinar indicator works perfectly, it has no issues, you can test it with other indicators, it works just fine.
