Topic: Candle Color Indicator Edit

Hi friends,

I am trying to edit Candle Color indicator. I only need to make buy/sell signals just opposite of the default. In default bullish candle giving buy (long) signal, bearish candle giving sell (short) signal. I need just opposite, bullish candle gives sell signal and bearish candle gives buy signal. How can i do it by editing this indicator code? Actually i did it but somehow lost how i did it and can not find again after all trials. Can somebody tell it me please.

Re: Candle Color Indicator Edit

You don't need to do anything, you select it by logic. You define only long condition in FSB, so you want black bar for longt, therefore you choose "Bearish Candle formed".

Re: Candle Color Indicator Edit

Interesting, i didnt know in FSB only defining long position. I understood now. Thank you footon!
