When you set up a "private" array you cannot directly compare that
array with any array set by AFL. If you look at DateNumOfBuy[0] which
has only a few members with Buy array which may have hundreds then you
ill be comparing similar it to buy[0[], not what you wnat. Unless you
use a loop and compare the date in your array to the one in the bar
they will never be in sync. Using a loop in this way will make auto
analysis much more difficult or totally incorrect.
Buy why don't you just use buyprice, also sellprice, coverprice and
shortprice, to keep your trade prices and then plotshapes to show them
on your chart? This will keep all the arrays in sync.
Set buyprice to the value of C when the condition is true. For example,
if you use MA crossing then put the value of one of the MAs in
BuyPrice. If you use C it will end up being the close of the bar, not
necessarily the price when the condition was true. Even the MA price
may not be exact but it will be much sloser to the real trading value.
buyprice = iif(buy condition, value when the condition is true, 0);
then chart the buy point with either
PlotShapes(Buy * shapeUpArrow, colorgreen);
PlotShapes(iif(Buyprice, shapeUpArrow, 0), colorgreen);
Plot the buyprice so you can click on the bar and see its value,
plot(buyprice, "\nBuyPrice", colorblack, stylenoline | styleownscale);
Setting buyprice will also let you use it in automatic analysis.
