Vice versa for short.

Let’s try the strategy right away!

The stock used is the SPY ETF so, having a bullish bias, I will avoid opening short positions with the same strategy.

We will enter with a fixed number of 100 shares, without any volatility filter to make the code as simple as possible.

Defining an exit rule will be necessary. I will insert a classic exit in time after x bars:
If barssinceentry (0)> = time_exit then sell (“TE_L”) next bar at open;

Being a trend-following strategy, it will be convenient to remain in the market for several bars, say ten days and I will insert a catastrophic stoploss of 1000 dollars.

Here is the code for EasyLanguage and PowerLanguage:

//Ema Cross – Tutorial EasyLanguage and PowerLanguage for TradeStation and MultiCharts

Input: MA_length(20), N_Shares(100),time_exit(5),Money_Stop(300);
vars: MA(0);


If MA>MA[1] and MA[1]>MA[2] and Close[1]>MA[1] and Low<MA and Close>MA then
Buy (“Entry_Long_Tutorial_Example”) N_Shares Shares this bar on close;

If barssinceentry(0)>=time_exit then sell (“TE_L”) NEXT bar at open;
