Best practices when creating a strategy

[keithmj]

I have a few indicators, of which I'm using their calculations to create a strategy. I'm wondering which of these is the most efficient approach.

1) I can copy the code from each indicator and mash them all into one strategy. Once done, I could remove the individual indicators from my study set since they are all now in the strategy.

2) I can copy just the calculations from the indicators and mash all those together. I'd change all my "plot" to "def" and remove all the formatting. In this case I'd need to leave the individual studies in the set.

If I go with door #1 then changing the user options will affect the study and the strategy. If I go with door #2, I'd have to change user options in both places, yet the system might run faster?

I currently have door #1, but the more I add the more the system seems to bog down. Which approach do you guys take?

Thanks!

different people may have different experiences and advice. here is mine.

1 and 2.
copy entire TD study code into my code.
if a plot variable will be used in other formulas, i change it to def. comment out original lines. don't delete anything until a couple versions later. might need something. easier to remove a #, than to type out plot code lines.

i try not to use plot variables in other formulas, because i might disable the plot. add yes/no inputs and new plot formulas to control what is plotted.

someone can check this, but i have thought that,
try to limit the quantity of formulas that have to read data external of the study. which means to copy the study code into yours and not just reference the study name in formulas.
instead of having close used 20 times, set a new variable to close , then reference that new variable.
def c = close;
close has to read data from a source external to the study.

i would think 2 would bog down tos, as there are 2 copies of the studies , reading data and doing the same calculations.
but on the other hand, when i add many bubbles, it tends to delay when chart objects are drawn. so try to limit how many things are drawn on a chart.

experiment with different ways of doing something and see what works for your project.
