why mq4 indicator with 2 buffers doesn't work

[guyha04]

I've created an ea from an indicator with two buffers, i put the
indicator on a chart and it clearly shows arrows.
but the ea i created 0 buffer for buy 1 for sell , but the ea doesn't open trades.

Some indicators repaint or dosnt draw the arrow on current bar but previous of a range of candles, other uses objects to draw them , try both indicator visable block and indicator appears, and try with different candle ranges back to see it it does anything
