How to plot chart using only current day's data

Hi,
This has been driving me crazy. Any help is appreciated. How to plot chart using only current day's data ?
For example if I plot EMA using intraday data, it by default takes even previous day's intraday data into effect. This results in huge lag at the start of the day.

Thanks,

Don't use indicators, use only Naked Price Action, will you see the lag ?

Hi Kelvin,
What do you mean by naked price action ?

Thanks,

Price action is behavior of price with respect to time due supply and demand which does not involve any indicator. Trader are applying different technique to interpret the action into their setup. Search this forum you can find many good thread on PA / Price action

First clear all the indicators for all windows. only price is used. Check whether any lag as what you stated the ema is lag.

The amibroker using memory block to store the ema value, it is very fast (in nanosecond) when back fill.

But first thing you complain is ema. Have you check out your hardware before make any comment :
Is your Internet and computer to your data feed provider is OK ?
If not, can that be possible that your data is delay due to error recovery to backfill to the memory resulted the ema is slow.
So far no information is shown that you are looking into this direction.

These are the basic thing you need to check out yourself.
