Hi Guys,
So we've just discovered this wonderful software and been trying to develop a trading system.
When we try to backtest this, it seems that it's trading fairly low(we set the time to 1yr) also, if I check it on the stock charts, it seems to not get ALL of the buy signals that were supposed to be compliant with our conditions.
Here are the conditions:
Buy Signal
#1) Green Candle
#2) Green Volume - Above 5M pesos
#3) Above MA20
Sell Signal
#1) Red Candle
#2) Red Volume - Sellers are dominant
#3) Below MA20
Attached is the code that I made. (EDIT: Di pala na-attach, see below for the code)
Here is a screenshot of an example where it didn't show any buy or sell signals: https://drive.google.com/file/d/1KTUXAKnbLbfDj4_oNhvsddAY9NYnvHLn/view?usp=sharing
(It's a google drive link)
I'm not entirely sure if I even did the code correctly for the parameters, so I hope you can help me correct anything from this. 😀
Anyway, what I've tried so far is adjusting the BreakHigh/Low value and even the BreakOut/Down Signal value. There are still parts of the charts that don't show any signals.
Hope you can help me with this! 🙂

can you post your script here so we can troubleshoot it?
@vanguardai I edited the thread. The Attached file didn't upload I guess. anyway, the code is within the post now 😀
I checked and the script looks to be working as intended, in those times PHR had low volume so a buy signal won't trigger. Volume also refers to shares traded so it might vary per stock, you can change this into value by modifying the formula to (last * volume).
For the backtesting portion, my guess is that you don't have a big enough initial cash or the max amount per trade is too big. In the event you have a buy signal but not enough cash in the portfolio, you won't be able to execute that buy signal since we are trying to simulate live trading. You can also check the trade logs if that's the case.
I did a sample backtest against the PSEi and looks like it works fine and more importantly, performed better than the PSEi so congrats! ?
The version below includes MACD crossover as part of the buy signal.

@vanguardai So i'm kinda overthinking this huh? haha Thank you for the feedback and adding MACD as part of the buy signal! 😀
