Algorithm is trading too often

I would like my algo to buy a certain percentage of my portfolio, (say 30%) when it breaches its moving average. The problem is that a few times a day it will trade 1/2. This is completely unnecessary and will run up my brokerage fees. Does anyone have any potential solution for this issue?

*1/2 shares per day


Hi James,

It is based on your trading logic and how you place orders. You requested the minute data for assets in Initialize(). Then each minute new data point will be pumped into OnData(). If the trading condition is satisfied, new orders will be placed. 

There are many ways to reduce the trading frequency. For example, you can add this statement 

if not self.Portfolio.Invested:

Then new buy order will be placed only when you don't have assets invested in your portfolio. If you want to trade only once per day, you could use to control the OnData(). For your reference, this is a simple example

Perfect, thanks!
