One Percent a Week

Published by Glitch on 2/18/2025

This strategy runs on daily TQQQ data, attempting to capture a one percent gain per week. Since it legally "peeks" into the future to determine if the next bar is the end or beginning of the week, it doesn't produce alerts. Additionally, it peeks at Monday's open price, and places a limit buy order 1% below the open. So, if you trade this, keep that in mind and watch the Monday open, quickly placing your limit buy 1% below the open. The next day, place a 1% profit target GTC, and if the position profit goes below 0.5%, make this a breakeven exit. Finally, if the position is open by end of week exit it at Friday's close.

C# Strategy Tips

• Strategies are coded in the C# language and utilize the Microsoft .NET framework.

• Your Strategy is a .NET class derived from the UserStrategyBase base class.

• Override Initialize to perform one-time tasks like creating indicators.

• Override Execute, which is called once for every bar of data being processed, to implement your trading rules.

• Check the Online WealthLab Framework Reference for documentation on classes and methods.
