# Create Strategy to open position on 3rd candle above 9 SMA

Sorry, I'm just no good at deciphering the language at TOS Learning Center. All I want to do is to have my strategy issue a BUY when the 3rd candles opens above the 9 SMA and CLOSE my position when the candle finally closes below the 9 SMA.

So basically, to open: candle 1 crosses above 9 SMA, candle 2 closes above 9 SMA, candle 3 (buy) opens above 9 SMA. Sounds so easy but I just can't figure it out.

My attempt:

Code:
``````#
# TD Ameritrade IP Company, Inc. (c) 2017-2020
#

input price = close;
input length = 9;
input displace = 0;

def AvgExp = ExpAverage(price[-displace], length);

def condition1 = close[3] crosses above AvgExp;
def condition2 = close > AvgExp;

def buy = condition1 and condition2;
def sell = close crosses below AvgExp;

AddOrder(OrderType.SELL_TO_CLOSE, condition = sell, price = close,1, tickcolor = Color.GREEN, arrowcolor = Color.GREEN, name = "Cover");``````

@BenTen wow! How did you do this so fast?! Is there somewhere besides the TDA Learning Center to get instruction? Thank you for your help!! Very much appreciated

i get no arrows

@poststreet The original poster was asking for a backtesting strategy. This is not a regular indicator. It won't plot any arrows on your chart.

@poststreet Now you gotz arrows:
Code:
``````# Buy 3rd candle above 9SMA
input price = close;
input length = 9;
input displace = 0;

def AvgExp = ExpAverage(price[-displace], length);
def condition1 = close[3] crosses above AvgExp;
def condition2 = close > AvgExp;

def buy = condition1 and condition2;
def sell = close crosses below AvgExp;

def arrow_plots = high – low;
def plotHigh    = high + arrow_plots * 0.3;
def plotLow     = low  - arrow_plots * 0.3;

plot sellarrow = if sell then plotHigh else double.NaN ;

sellarrow.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
sellarrow.SetLineWeight(2);
sellarrow.SetDefaultColor(color.magenta) ;
