Absolute Strength

Description

Follow my cTrader Telegram group at https://t.me/cTraderCommunity; it's a new community but it will grow fast, plus everyone can talk about cTrader indicators and algorithm without restrictions, though it is not allowed to spam commercial indicators to sell them.

As requested, I made the Absolute Strength Indicator.

Mode = 1, RSI-Like computation

Mode = 2, Stoch-Like computation

For anything, contact me by commenting below or by joining the telegram group linked above

... you can also replace/add to avoid wrong mode values:

 

        [Parameter("Mode", DefaultValue = 1, MaxValue = 2, MinValue = 1)]
        public int mode { get; set; }

Thanks for sharing.

I noticed that the mode parameter was not working correctly, and Mode =2 was is not showing 

All you need to do is just void this line

 mode = mode > 2 ? 2 : mode < 1 ? 1 : mode;

as:

 

// mode = mode > 2 ? 2 : mode < 1 ? 1 : mode;

Now both modes are showing

Hello,

I found this gem that works like an absolute strength indicator. But the mq4 converter is buggy. Is there a way to turn this indicator into calgo. Thanks in advance.
