2, TFILT minutes, filter the data within the specified time period, and the data outside this time period is invalid.
Usage: TFILT(X, D 1, M 1, D2, M2), such as TFILT(CLOSE,10401,1025,/kloc-0. 1345) means that the closing price is valid from 65438+ 10/day 1 0: 25 to June 13:45, 2004. The period is in days, and the time division is 0.
So, if you want to get the highest price from 9: 25 to 65,438+00: 30 on June 65, 2004 through a communication function or a combination function, use: (high, TFILT(CLOSE, 20040 10 1 0925.
3, REF points to the front, referring to the data of previous periods. Usage: REF(X, a) refers to the value of x before a period. For example, REF(CLOSE, 1) represents the closing price of the previous cycle, which is the closing price of yesterday on the daily line. So, if you want to get the data of the highest price from 9: 25 to 65, 438+00: 30 on June 65, 2004 through a communication function or a combination function, use: REF(HIGH, TFILT(CLOSE, 20040 10 1 099).

At that time, your task was to learn how to write some common concepts, such as the listed volume and increase. Perhaps some of them are the basic morphological features to be used in the formula writing process. The volume of 1. 1 did not increase last night 1 ten times vol/ref > 2；;

There are three or four important functions in the system function because of IF, IFF, IFN and TESTSKIPJohn. Please note that the parameters of the function of the communication letter are calculated and then passed to the function immediately.

5.f means that the increase on the last trading day is much higher than 8: 00, if the closing price is displayed at the end of the service desk. At that time, for example, the usage of these three functions, the example formula DRAWFIX formula name DRAWTEXT_FIXISLASTBAR, 0.
