I suggest you add some basic requirements, such as how much is the stock price below? How much is the circulation disk less than? What is the net capital (greater than the risk of excluding ST)? This will reduce your screening time.
Come in, master! Please help me to write the stock selection formula of Tongda letter when the K-line entity is less than 5% that day! Thank you ABS(O-C)/REF(C,1) *100 <; 5; Compared with yesterday's closing price
For four consecutive days, the K-line did not rise or fall by more than 3%. You should mean stocks that fluctuate within a narrow range. Look:
XG:HHV(H，4)/LLV(L，4)& lt； 1.03;
For four consecutive days, the increase or decrease shall not exceed 3%;
XG:COUNT(BETWEEN(C/REF(C， 1)，0.97， 1.03)，4)= 4；
How to write the stock selection index of straight flush "stocks that have risen more than X% in a single day in N days"? Increase: = (c-ref (c, 1))/ref (c,1) *100 > x;
Count (increase, n) =1;
Willing to ask the master to write a stock index! Thank you S 1:=IF(CODELIKE('300'), 0,1);
S2:=IF(NAMELIKE('S ')，0， 1)；
S3:=IF(NAMELIKE('* ')，0， 1)；
S4:=DYNAINFO( 17)>0;
XG:O/REF(C, 1)> 1.03 and S 1 and S2 and S3 and S4;
Please master the stock selection formula: 60 lines are greater than 120 lines, and not more than 30 days. Your situation is not very good.
From 1 day when Line 60 crosses 120-29th, a signal will be sent out every day. Do you want such a signal?
Please write a 100 daily shrinking stock index, thank you. Shrinkage rate: volume
100 in brackets can be changed at will.
Note: If there are no other conditions for your stock selection, if the newly listed stocks continue to shrink from the next day, they will signal continuously.
A simple judgment method is not ideal:
WX:= Ma (c,100);
Shrinkage rate: volume
The shrinkage will only be prompted after 100 days. Modify 100:= MA(C, 100) in WX to become the monitoring cycle you want. Maybe you can think of a better optimization method.
Please write down the stock index dif: = EMA (closing, 12)-EMA (closing, 26);
DEA:=EMA(DIF，9)；
MACD:=(DIF-DEA)* 2；
Ignore the above formula. Write the formula according to the train of thought and modify the formula. Early warning, conditional stock selection. Decrypt the formula and remove the time limit. Click my name or the following (icon) with the mouse, and press enter to see the Q custom formula.

The above is a communication letter. If you don't need correspondence, you can ask me.
Excuse me, how far can four square copper wires (multi-strands) be sent under the voltage of 220 without the line loss exceeding 10%? Thank you. The load, that is, the current, determines the line loss. If the current is small, the voltage drop will be small and it will be sent far. First, determine the load current and calculate the impedance of the 22 volt voltage drop, and calculate the line length. Sometimes the actual value differs greatly from the calculated value.
