You want the buy/sell orders to be [1], not [-1] or even 0, since the MA_Max and min are already triggering on an index of -1. That means that unless you have the buy/sell orders at [1] then the backtest results will be way off, since it will have you predicting the future. See my previous posts on this thread replying to Summies who made the same mistake (which was also made in earlier pages of this same thread and pointed out by Mashume and others.)

addOrder(OrderType.BUY_AUTO, MA_Min[1], open[-1], shares, name = "BUY");
addOrder(OrderType.SELL_AUTO,MA_Max[1], open[-1], shares, name = "Sell");This code was meant to just be a strategy, not a pretty indicator. The prettier indicator that the strategy is based on you can find in Mashume's original code or elsewhere in this thread. You could run this strategy and the indicator at the same time if you wanted as well.
I could not get these codes to work, Could someone please help, I cut and Paste the code, went to Studies, Edit Studies, Create ( studies ), Deleted the Preset code, and Pasted the new Upper Code, Save and OK then Create another one for Lower code. But it doesn't work neither. Please help or if you help with a Video would be great, Thanks so muchAs I was looking at the Hull Moving Average, it occurred to me that taking the local minimums and maximums might not be the most effective use of it's smooth nature. Nor did it seem that a moving average cross over would provide timely signals.
And then I remembered that I used to teach physics and calculus and decided to look at rates of change and that lead me to...
CONCAVITY
which is nothing but the second derivative of the function (if you remember or not)and so this indicator was born.
It is in two parts -- the upper which is the Hull Moving Average with the addition of colored segments representing concavity and turning points: maxima, minima and inflection. The last of these are of the greatest interest. The second part is a plot of the calculation used in finding the turning points (which is roughly the second derivative of the HMA function, where zero crosses are the inflection points.
UPPER INDICATOR
Upper HMA colors:
- Green: Concave Up but HMA decreasing. The 'mood' has changed and the declining trend of the HMA is slowing. Long trades were entered at the turning point
- Light Green: Concave up and HMA increasing. Price is increasing, and since the curve is still concave up, it is accelerating upward.
- Orange: Concavity is now downward, and though price is still increasing, the rate has slowed, perhaps the mood has become less enthusiastic. We EXIT the trade (long) when this phase starts. Very little additional upward price movement is likely.
- Red: Concave down and HMA decreasing. Not good for long trades, but get ready for a turning point to enter long on again.
Upper Label Colors:
these are useful for getting ready to enter a trade, or exit a trade and serve as warnings that a turning point may be reached soon
Arrows are provided as Buy and Sell and could perhaps be scanned against.
- Green: Concave up and divergence (the distance from the expected HMA value to the actual HMA value is increasing). That is, we're moving away from a 2nd derivative zero crossover.
- Yellow: Concave up but the divergence is decreasing (heading toward a 2nd derivative zero crossover); it may soon be time to exit the trade.
- Red: Concave down and the absolute value of the divergence is increasing (moving away from crossover)
- Pink: Concave down but approaching a zero crossover from below (remember that that is the entry signal, so pink means 'get ready').
LOWER INDICATOR
For those who prefer less cluttered uppers, I offer the plot of the divergence from expected HMA values; analogous to the second derivative in that the zero crossovers are of interest, as is the slope of the line. The further from zero, the stronger the curve of the concavity, and the more likely to reach a local minima or maxima in short order.
Miscelaneous
If you find that there are too many buy and sell signals, you can change the length of the HMA (I find 34 a happy medium, though 55 and sometimes 89 can be appropriate). You can also play with the value of the lookback, though that will slow down signals.
This works well on Daily timeframes as well as intraday candles.
I set it up with High + Low / 2 as the default so that it shouldn't wait for close prices. That may not be appropriate to how you wish to trade.
Comments welcome. Let me know how you use it, how it works for your trades, and whether it made your head hurt trying to remember your calculus.
Happy Trading,
Mashume

Do you have a systematic way of exiting your trades? If so, I'd be happy to setup your system as a strategy so we can backtest the results.
TMO ?
@TraderKevin I typically draw fib extensions and exit at one of the relevant levels on the Fibs. The other way I exit is when prices start coming close to the 20 SMA. So essentially, there is no hard coded exit plan that I adhere to. It is more fluid. And since I scalp, I also exit if the ticker meets my $/% targets
