and which time frame are these charts....can anybody know? if you cannot make out, what is the point in trading one time frame rather than another?
For day trading US equities, I consider a 5 minute high or low to have significance. On US Globex Futures or Forex, I consider a 30 minute high or low to be significant. I formulate part of my short term trading plan from daily charts, as I consider the prior day's high and low to be potential support/resistance. Wide/narrow range days on daily charts will also influence my trading decisions, as the axiom "enter on narrow bars and exit on wide bars" applies here to me. For swing trades, I look for a correction and will try to determine the trend resumption day. On the presumed trend resumption day, I use a deviation from the day's opening in the direction of the underlying trend as an entry signal. I believe it is beneficial to be aware of multiple time frames in an attempt to maximize Risk/Reward.
Your question is not clear. There are cases where the data feed quality and internet are horrible, and you get jerky chart. There are cases where the buyers / sellers are confused/undecisive etc etc ended up you get jerky chart. I find Heating oil, RB gasoline futures tend to have this 'problem'. either case, it is difficult to trade.
If the chart looks noisy, try to look at it from a key price levels perspective, on a different time frame, wait until the chart looks less noisy, or trade another instrument.
There is no noise on any chart. Only price movement. You can trade any chart you wish if your brain can interpret things fast enough and make fast enough decisions. Smaller time frames give more entries and exits for price action trading.
"is this noise in these charts?" You are the guy who just posted in another thread that you didn't need to know why markets move as they do, right? The contradiction must be hard on you. At any rate, others (above) have mentioned time frames. Think on that a bit. "One trader's 'noise' is another trader's target-rich environment."
