Ziko re 1min chart. As you know, I am a fan of 1-10 min charts because the longer term indicators can be adapted to the faster time frames by increasing the parameters, and signals become realtime instead of end-of-day. I dont find much in cyclically based patterns with wavelengths under 2.5-3.5 days, and 1min charts dont have the computing capacity to deal with 3 days, as the stockchart parameter maximum is approx 600. The visual chart will extend much further. I use 1minute charts only for the OBV but visually monitor the action. Oddlot
