help defining a trade rule with excel

ALFASSY 

Hi again I used the match index function to get the time when the market price first touched the pivot +0.5 and it worked but i have a little question. this is what i have done:ac3 is the pivot y3 =AND($J$41-INT($J$41)>TIMEVALUE("16:30:00"),OR(CROSSFROMABOVE(E3:E4,AC3+0.5),CROSSFROMBELOW(E3:E4,AC3+0.5))) h13=INDEX(A3:A30,MATCH(TRUE,Y3:Y30,FALSE),1) a30 because i use 15 min bars chart and i only need the last 6 hours h13 gave me the time of the last crossover in the range(a12). but i want the time of the first crossover in the range(a18). how can i get that?? another question: because i use 15 min bars chart, when h13 gives me a time i don't know where inside that 15 minutes it happened. how can i get a more accurate time??? my idea is opening another chart of 1 minute bars and then my offset will be less then a minute, which is acceptable. do you have a better idea? thank a lot in advance!! have a nice day!

Since SC worksheets are in descending order, try using a match_type of -1, not FALSE.
h13=INDEX(A3:A30,MATCH(TRUE,Y3:Y30,-1),1)
This should give you the first crossover and not the last crossover.

Your idea of using another chart of a shorter timeframe, 1 min as you suggested, is the only way I know to get the time inside the 15 min bar. J41 updates with every price tick but I don't know any way to capture it at the moment another cell goes TRUE.

I don't think locking the state can lock a value. I've tried to do this without success. If you figure it out, I'd be interested to see your solution.
