Hi, I've been trying to post my entire code in a backtest b/c I could use some assistance but I can't even get it to build yet. Could someone please assist me with errors I am getting with this line of code preventing me from building my algo. Thanks!
if(!Portfolio["EURUSD"].Invested and currentPrice > smaDaily and totalTime == 0)
// Errors I'm getting on this line: ) expected
// Embedded statement cannot be a declaration or labeled statement
// ; expected
// Invalid expression term '>'

If you are writing in C# logical "and" in your if statement is & or &&, not the word "and".
& allows short circuit evaluation. Most of the time people mean &&. If you are unsure, most of the time use &&.

Ahhh, thank you, silly mistake. That will help me focus on the bigger problems with my code. Thanks for taking the time to look!

No problem. I need to correct myself though so wrong information is not propagated.
&& is short-circui evaluation
& evaluates both sides
opposite of my first post.

You can best download Visual Studio and then code there and then copy-paste back as you need data. This is a bit tedious, but it will speed up with avoiding typo's. Microsoft's intellisense will also suggest how to fix your code at some points.

Thank you for the responses!! I have been struggling for days on this. I was hoping to use it to learn. Since I can't get it even ready to backtest could someone copy and past the code I have attached here into their editor and give me some pointers. The logic was suppose to be: If uninvested, buy if above SMA, sell if below SMA. Set a profit target, if it hits re-enter trade according to SMA position. When trade initiated it starts a timer, which is main variable, number of days, in this case 10. If profit target hasn't been reached in 10 days, trade is closed, all profit orders cancelled. Then it re-opens base on SMA again and gets a new 10 days. etc.
