1) Fixed bug not always taking L2 trades in strategy tester (visually could see them but strategy entry would not always take it)
2) Added lines to show next buy price as well as the stop price (these are the dashed lines).
Couple things to note about this script so far, which vary slightly from the original turtle rules.
a) All entries to positions are triggered if the close > L1 or L2, NOT the high. This has an interesting side effect. If high crosses over the L1 or L2, but doesn't close above it, this extreme point (high of day) must be crossed in subsequent days to generate a trade. Backtesting, I like this as it forces the trade to really stretch and be bullish, also helps reduce some of the noise in this day to day trading.
b) The actually buy in trading view occurs at the open the next day.
