For knowing buying and selling strength of stock can we just consider all blue candles in 5 Or 15 Min time frame are buy and all red are Sell. Can we use Heikin Ashi Or normal which is better. As there is lot of Price manipulation with F&O some times even the Colour of candles are not giving correct picture & making confusing situation. This may be a basic question but would be helpful if some more refined information available on how to judge candles . Thanks
