Buyer Seller Rejection (BSR) indicator:

If a candle (irrespective of a bull or a bear candle) has a bottom wick (BW) length greater than top wick (TW) length, it should have a blue arrow under the low of the candle, indicating buyer strength.
If a candle (irrespective of a bull or a bear candle) has a top wick (TW) length greater than bottom wick (BW) length, it should have a red arrow on the high of the candle, indicating seller strength.
If a candle (irrespective of a bull or a bear candle) has a bottom wick (BW) length equal to the top wick (TW) length, it should have a yellow dash under the low of the candle, indicating neither buyer nor seller strength.

If I put this indicator on the chart, it should draw the arrows on all candles.  
It should have visualization setting so that I can display the arrows on certain time frames of my choice.
It should have settings for size of the arrow, color of the arrow, distance of the arrow from the low or the high of the candle.
That's it.  You should be able to do it in no time.
