Right TP, That's the way it is supposed to be. As at 12.28, 1M chart has only 10 Candles.... If there is price congestion, it can be even less.... And in all cases, the candles will be less than the TF, as 'inside bar candles' are ignored.....
The Renko chart has only 4 candles for the day whereas the japanese candle chart has 30+
