PHP Code:


			
if(currency_decimal == 2) OpenTriggerLevel = DoubleToStr(OpenTriggerLevel,2);

What I am attempting to do is have the EA automatically change the default OpenTriggerLevel from 4 decimal places to 2 when the user selects 2 (currency_decimal) from 4 in the EA setup. Such a change would have to take place on a currency like USDJPY which is 2 decimal places.

Evidently the compiler does not like the second ' = ' sign in the above statement.

With continued appreciation, Thanks in Advance for your input assistance!

MQL4 has predefined variable Digits which corresponds to number of decimal places of the pair.
DoubleToStr(OpenTriggerLevel, Digits);

the code is correct, look error in variable definition probably.

I tried this, but it still displays OpenTriggerLevel as .0004 versus .04:

PHP Code:


			
if(currency_decimal == 2) DoubleToStr(OpenTriggerLevel,2);

Still confused???

The problem of that statement is that the variable 'OpenTriggerLevel' is of 'double' type, while the function returns a 'string'. So, while the code is syntactically correct, it's semantically wrong, and I would believe that's why the compiler complains.

If you want to carry the string in a variable, you'll need a variable to do so. Otherwise you can use the 'DoubleToStr' function within the 'Comment' argument to replace where it currently says 'OpenTriggerLevel'. There it could say

PHP Code:


			
DoubleToStr( OpenTriggerLevel, currency_decimal )

and you wouldn't need the 'if ..' statement at all.

This is a great indicator except it keeps changing the name on the up and down trend lines, can someone change this indicator to make the name fixed so it does not change the trend whenever the trend direction changes?

and has anyone though of making news indicator so we can add news events with time and currency pair in the code and each time there is a news we get a signal, then later use that signal to start or stop an EA ? please let me know if someone did that already ?

Regards,
Alan

You find where it says

PHP Code:


			
price_p1=lap;

price_p0=lap+dhm/2;

price_p2=lap+dhm;

price_01=la0;

price_00=la0+dhm/2;

price_02=la0+dhm;

and change that to say

PHP Code:


			
price_p2=lap;

price_p0=lap+dhm/2;

price_p1=lap+dhm;

price_02=la0;

price_00=la0+dhm/2;

price_01=la0+dhm;

hi all, i've been doing some modding to the EA "10points 3". all is well EXCEPT i want to have the buy and sell run independantly. i.e. i set a max of 5 buys and 3 sell.. if one is maxed and the direction changes the aother may still open... i will not post the 10points3 EA here because it's all over this forum.. but could you at least point me in the right direction to seperating the buy/sell ?my lastest atempt almost worked but almost never cuts it!
