Hello krzysiaczek99, Please describe your issue in detail. What exactly are you trying to achieve? Could you please provide any examples from other platforms? Also please send screenshots demonstrating the issue if possible. I want to achieve possibility of backtest FOREX data. For example for 1 lo...

Hi all, Is it possible to switch chart type in EL script e.g for one value from optimizer to be OHLC and another RENKO? ChatGPT says its possible saying I can use SetChartType or ChartType but they don't compile. Yes, `ChartType` and `SetChartType` are common for both Easy Language and Power Languag...

Hello krzysiaczek99, That’s expected behaviour. If you’d like to optimize two strategies separately, you’ll need to put them into separate Portfolio windows. Having separate strategies in the same Portfolio window allows using different signals or broker accounts for specific symbol sets. But Money...

After running optimization from Portfolio Trader for two different symbols as different strategies number of bug was encountered. 1) Seqential optimization is not performed i.e. for each strategy. Instead sort of combitional optimization between two strategies is done even those strategies are separ...

Hi, I know that only primary instrument can be traded but we are talking here about backtest and optimization results not trading. The pourpose of this script was to make fully automated backtest on multiple symbols using exhausive optimization, by iterating over dataindex i wanted to do if for mult...

Hi krzysiaczek99, The FAQ that TJ pointed out does have the correct information for handling multiple data series, including function calls. The topic is not the most apparent to figure out for an easy language. It is ok to ask how to write the code but you included a function from John Ehler that ...

is my advice wrong?
or
your code does not work?

there is a difference.

reply was made as a solution to problem described in this thread and its not working. It feeds data from different instrument to EL script but it don't affect backtest or optimization results what is a subject of this thread

See post #5 https://www.multicharts.com/discussion/viewtopic.php?t=6929 Unfortunatelly your advice is wrong. After modifying code as below, backtest is still done on data1 even after setting idx = 2. So please advice how it is possible to change input data inside the script to get correct backtest ...

Can you just give example how my code should be changed to be able to iterate over different instruments using optimizer ?

See post #5 https://www.multicharts.com/discussion/viewtopic.php?t=6929 I simple want to iterate over dataindex to make multiple instruments backtest using optimizer. Optimizer results are faulty as well when you change dataindex to use different instruments. If I use the trick as in my last post a...

the same bug occurs also when such code is used:

if idx = 1 then Price = Close of Data1;
if idx = 15 then Price = Close of Data15;

and idx set yo 15

res15_1.jpg test1.jpg instr1.jpg res1.jpg res1_1.jpg Hi, I have following code: Inputs: dataindex(1), RSILength(14); Vars: oResult1(0), ObLevel(0.8), OsLevel(-0.8), Price(0); Price = Close of Data(dataindex); oResult1 = JohnEhler_My_RSI( RSILength, Price ); if oResult1 crosses under 0 then SellShor...

Hi,

I would like to have a communication between R and Multicharts. Is it possible to use Global Variable for it ?? i.e. if I will call Global variable dll from R will I have access to global memory used
by MC ?? Or maybe there is another method.

My fitness function is like this if (StrategyPerformance.TotalTrades > 200) { if (StrategyPerformance.AvgBarsInWinningTrades > 4) { return StrategyPerformance.PercentProfitable*StrategyPerformance.Profitfactor; } } Than im getting in optimization report Average bars in winner = 2 and total number of...

Hi,

I found the reason of the problem. During import of the data Big Point Value must be changed to 1, I have it set for MC 5.5. When i changed it to 1 from 10000, strategy started to work.

Thanks anyway, Krzysztof

I will try it. However if "Crosses under" would not work than AAA in my test would not be printed but it is. Beside the version difference that data was imported using "ASCII mapping". In working case of MC 5.5 it is fetched from global server. It should not matter as it is displayed and indicator w...

I have the old MC 5.5 and took strategy and data from it and imported to MC 8.0 but the same strategy on the same data doesn't generate trading signals at all. Data after import is properly displayed at MC 8, its not a problem to attach e.g. indicator to it. MC 5.5 generate trades with no problem fo...
