// I needed to test/verify the functionality for canceling an open limit order in a strategy and also work thru the pieces needed to set the position sizing so each loss is a set amount. 
// This is not meant to be dropped into a chart but rather gives the code/logic in order to use in your own script w/alerts or strategy. Hope it helps.

// Position Sizing 
//////////////////
// For each trade setup that fires in this scenario we want to set our total loss amount in USD, so every trade that loses is lets say $1 and the 2:1 target would be $2 in this example. 
// The math logic for this take the risk amount and divide by the stop percentage, take that number and divide by leverage amount chosen. Stop percentage is a variable below if questions on that. 
//
// Taken from @JoshuaMorris (shout out to the UK peeps) position sizing google doc so thank you sir. 
// Would be used if risking based on percentage of a portfolio. Leaving code snippets here in case that's the direction someone wants to go.
