You can use on any symbol.
The script will follow price action principles. It will calculate the absolute value of last candle and compare with actual candle. Colors are:
- Red - If the actual candle absolute value is higher than previous one, and the price is lower than last candle. It would be a short entry.
- Blue - If the actual candle absolute value is higher than previous one, and the price is higher than last candle. It would be a long entry.
- Black - The actual candle absolute value is lower than previous one, so there is no entry.
If there is a candle that is higher than previous one, and both high and low values are outside boundaries of previous one, it will calculate which boundary is bigger and will apply the collor accordingly.
