A pre-made indicator does not read the values of the 1st previous (closed) candle properly

Hello,
It's very glad to contact with you, first.
The followings below is my difficulties, and hope you to read and help.

I have a pre-made indicator that shows simple arrows for Buy / Sell Entry.
This pre-made indicator does not read the values of the 1st previous (closed) candle properly.
And the main chart (trading time frame) is M1 chart, and it uses HFT (Higher Time Frame) likely as M5 and H1.
At this time, calculations in M5 and H1 are for the trend.
But it does not calculate the conditons in a right way.
For example, the calculation is right, and sometimes not right.
I think it misses the calculation of M5 and H1.
It does not work properly even if there are only simple 4 conditions in Buy Entry.
I don't know exactly why it happens.
So, I hope it to read exactly the values of the 1st previous (closed) candle of M5 and H1.
Could you please fix this simple indicator to work properly?

Best,
David
