My ea only contains between 300 to 500 lines. It's a simple one. Seems people are having more complicated eas

is there any relation between number of lines and profitability of an EA ?

Of course, here is the formula :

In this physics example, a ball with uniform acceleration () and initial velocity () is seen at intervals of 0.05 second, with distances marked. If the ball moves a distance the time satisfies the equation: where represents an unknown, and , , and are constants with not equal to . If , then the equation is linear, not quadratic. The...

When I set out to properly write and EA I decided that I wanted to first code all the functions that any EA I coded would need,  so I did just that,  I coded a set of standard functions to do the following:

Take a screenshot,  Error reporting to screen and via email, Draw Fibonacci retracement,  Mutex to avoid trade context busy, Trade Sizer - calculates position size based on %age risk, PlaceTrade - determines if a order should be Market or Pending and is valid then places the trade,  CheckTrades - checks for missing SL & TP checks for pending orders becoming invalid, Spread MA function, Watchdog - checks for losing runs of x trades or more checks that losing trades are losing the correct value, trading error handler, Comments as Labels, Status messages

these functions are all reusable and amount to a couple of thousand lines of code . . .

to know the relation of complexity to profitability

Seriously ? There is no relation between complexity and profitability. And there is probably neither relation between the number of lines of code and complexity.

Anyway if someone would like to check this, he can make a study based on the Codebase.

personal opinion

i feel the more lines of code means more complex.

another things is to check if profitable ea are simple or more complex

Sorry doshur - there is no any relationship between number of lines in the code and profitability (usefulness) of indicator or EA for traders.
