Someone asked me Why I use Black and White colors for mt chart | GTC - Good Trading Calls

Someone asked me Why I use Black and White colors for mt chart.
Is it for good look ? Decency? Or what?

I replied, I use B/W because it is easier to print my trades, charts, journal using B/W printer.
Also, Colors dramatically change your performances. Even the different shade of white for me, changed my performance greatly.
You might think it’s stupid or etc. But if you have not journalised your trading then you do not know about it yet.

Do it Once.
