I have the following code and could use some assistance. The code below will constantly print out the "bid" and "ask" price of a specific Stock Option that I define in the string. If the price reaches my "Profit Target" then it will close the trade for a profit. If the price reaches my "Stop-loss" then it will close the trade for a loss. This works out well.
What I am now trying to do is create a "Trailing Stop" once my "Profit Target" is reached. I am trying to accomplish this by creating another function (might not be needed) where it will be constantly checking the "bid" and "ask", but it will only assign the value to the variable IF the "bid" or "ask" is higher than the current high for the variable. This way I can then incorporate it into the Main function and close the transfer if the current price of the stock option is say 20% lower than the "high bid" or "high ask" of the day.
Would this require to run another script "concurrently" that is writing the variable? Essentially, I am trying to get Go to create a new variable that only gets updated with the price if the current bid and ask are higher than the price that is currently associated with the high bid and high ask variable.
I hope this makes sense. Any direction of documentation I could look at to help me accomplish this would be an idea.
