Summary Finally, I would like to compare the speed of using the function with or without in the search for orders For this reason, we use the same version to test the Everytick mode 10 times in a row The results of our own calculations when using the MetaTrader software to calculate the time and time are as follows: Smart Trading 10 tested times (mm:ss) CrossMACD_beta (without the function) 07:42CrossMACD11:37DoublePending_beta (without the function) 08:18 Contains function)08:18DoublePending09:42As you can see in your table, the smart trading program using functions is slightly slower, which should be reasonable as a price to pay for making the source code easy to understand anyway, everyone has the freedom to use functions or not
