my chart doesn't look like this; Am I missing something here?
You need the News indicator from
thank barnix for all your effort here, but never mind I see it's not getting me there. Now I'm having trouble with the news indicator it wont attach. Why is it that the speed indicators need to work together with your news one; can't we just have one that works as is? just trying to figure it out. Anyhow, thanks again.
Several months ago I wanted to use scalping with asctrend system in elite section. I described Igorad the following:
- let's imagine that price is the vehicle driving by some crazy driver without speedometer inside the vehicle. So, the driver does not know the speed. Vehicle is stopping trying to change the direction, or moving too fast sometimes and coming back and so on. Is it possible to create Speedometer indicator for this vehicle?
So he created this indicator (attached). You may see everything with new ticks. I tried it but realized later that it should be a system with many indicators and one indicator is not enough.
Later on Kalenzo or Raff coded some good indicator to estimate the speed (in public thread somewhere) but not for scalping sorry.
Later on somebody created MACD_ticks (not exact name of the indicator, sorry) and so on. It was posted on some public thread as well.
Could you explain how you would have considered using it as a system for scalping. The use I make of it is only as a filter, meaning, not to take the trade when to slow, or exit when the move against your profit is too fast.
I tried to use it and realized that we need some more indicators same as ma_speedometer, MACD_speedometer and so on. It should be trading system. One indicator is not enough.

a-random, time-varying acceleration
T-is the time between step k and step k+1
The question which is addressed by the Kalman filter is this: Given our knowledge of the behavior of the system, and given our measurements, what is the best estimate of position and velocity?
