dear mldaen, could you modify the indi name from,
trend direction and force index - smoother 4_4
because i get this error when loading from icustom
2016.12.06 04:25:09.112 cannot open file 'C:\Users\Fabio\AppData\Roaming\MetaQuotes\Terminal\B8D2F3EE1E32D796BE42768EB957B2D5\MQL4\indicators\trend direction and force index - smoother 4_4.ex4' 
detail for the call are in
This is the proper name "Trend direction and force index - smoothed 4_4" and working with me.
your int,double,string and bool are not right as per my understanding
i don't have icustom call because i don't have such EA nor am coder .... but i read some where that "int,double,string and bool" are handles like this . (moderators can better guide us)
int = integer – this is a normal „number“. Example: 1, 15, 521
double = a number with decimal points. Example: 1.154, 0.0144, 255.145.
string = a word/phrase. example: „BuyOrder“, „OrderSend placed successfully“.
bool = either false or true.
You can give in the indicator window any "name" but even there where that picture was pasted (in the THV system thread at FF) there is no such indicator and never was. Displayed name does not make an indicator
If it did exsist, it apparently was a 7+ year old crap repainter anyways
