First try to code a strategy

Ok so I’ve been trying to learn the coding language in PRT for the last few days and had an idea, which is probably horrible, but I am mainly trying to write it for learning purposes and would like your input in how to write it correctly. I want to run it in ProBacktest. I will first write in plain English what it is that I want put down in code. My Bull Setup and Exit BullSetup = RSI 14 should be below 20 BullTrend= Close should be above MA50 BullExit = RSI 10 should be above 80 My Bear Setup and Exit BearSetup1 = Close today should be lower than close yesterday and the close yesterday should be lower than close 2 days ago. BearSetup2 = The percentagechange (measured close to close) today should be equal to or less than the highest percenagechange in 4 days. BearTrend = close should be less MA100 BearExit = when close cross under MA20 Rules If condition ‘’BullTrend’’ And ‘’ BullSetup’’ both are met I want to buy the next bar at market. If this buy statement is not true and the 3 bear conditions (BearsetupA, bearsetupB, beartrend) are all met then then I want to short next bar at market. Then I need a code that checks if I have a position or not (either long or short). And if I have a long position and the ‘’BullExit’’ happens then I want to sell at next bar at the market and if I have a short position and ‘’BearExit’’ happens then I want to cover my short So what I have coded so far is this: // Definition of code parameters DEFPARAM CumulateOrders = False // Cumulating positions deactivated RSI14 = RSI[14](close) MA50 = Average[50](close) RSI10 = RSI[10](close) MA100 = Average[100](close) MA20 = Average[20](close) Percentchange = Variation(close) //Bull Setup and Exit Bullsetup = (RSI14 < 20) Bulltrend = (close > MA50) Bullexit = (RSI10 > 80) //Bear Setup and Exit Bearsetup1 = Close < Close[1] AND Close [1] < Close [2] Bearsetup2 = (Percentchange[0] = Percentchange[4]) Beartrend = (close < MA100) Bearexit = (close CROSSES UNDER MA20) // Conditions to enter long positions IF bulltrend AND bullsetup THEN BUY 1 CONTRACT AT MARKET ENDIF // Conditions to exit long positions IF bullexit THEN SELL AT MARKET ENDIF // Conditions to enter short positions IF bearsetup1 AND bearsetup2 AND beartrend THEN SELLSHORT 1 CONTRACT AT MARKET ENDIF // Conditions to exit short positions IF bearexit THEN EXITSHORT AT MARKET ENDIF I am sure many things are wrong but I have a specially hard time figuring out how to write bearsetup2 (the percentagechange). Hope somebody can give me some advice on what is wrong and how to fix it. Best regards

Sorry I meantB

Bearsetup2 = (variation = highest[2](variation))

I don’t have my platform open at the moment and I have not used the indicator you mention before – but you can use the output of any indicator (even ones you create yourself) in strategies by calling them.

In your example I think this would be overcomplicating things as it is such a simple calculation.

Are you aware of the ProRealTime programming language documentation that can be found here or under the ‘Help’ menu on this site?

It is a great reference source.

I actually didn’t see that program language documentation source before. The only reference I was using was the 3 PDF manuals which can be found under help in ProRealTimes homepage. But those are a bit cumbersome to use as reference. I will be using the documentation that you sent as a reference from now on.

Thank you Vonasi!
