Auto adjust for 5 decimal brokers

I thought I read somewhere there was a snippet of code to include in an ea or indicator that would automatically adjust decimals between brokers that have 5 and those that don't.

Does anyone know the code. I have some price indicators that look a bit wacky. (ie spread = 30.0 pips rather than 3.00 pips)

Thank in advance to anyone that can help point me towards the code if it exists.

double xecn;

//Put at top of code
xecn=1; if(Digits==5||Digits==3){xecn=10;}

Anywhere you use the TakeProfit, StopLoss or Slippage - It will make your code work with any 4/5 digit broker automatically.

before:
TakeProfit*Point

after:
(TakeProfit*xecn)*Point

OK I tried that. I'm pretty sure I did it correctly but it didn't work (gave errors on compile)

Maybe someone can mod this file as I'm not much of a coder

You cant change the number of digits your broker sends to you. that code snippet just lets you not worry about it when placing orders. you can't disable 5 digit. You could print numbers with NormalizeDouble(x,2) for numbers with 3 digits. And (x,4) for 5 digit numbers but theres no way to cut it off.

Yes I understand that. The price the way it's displayed on my chart with the particular indicator is what I am trying to modify.

It shows 30.0 pips for 3.0 pips etc.

Hi guys,

I just noticed that the above indicator was not showing fractional pip spread on JPY type of pairs so I updated it to be fully functional. See pic for USDJPY displaying fractional spread after my edit. Though I'm not sure why Cja's indicator was renamed to "Information.mq4", here's the edit (name changed to prevent confusion)...

This is great, thank you.
What about Spread?

I know if normally with 4 Digits Brokers (Number of digits after decimal point = 4) Spread would normally be like 3 - 12 so for indicator display I would do a /xecn but in the code still do *xecn on the Spread, correct?

There is talk about 6 Digit forex quotes but I think they are only referring to total number of Digits. So a now 5 Digits broker e.g. EUR/USD 1.23456(6 Digit) is still the new 5 Digit broker because in MT4 they count the digits after the decimal place.

nope. for spread you do a divide.

assuming a spread of 2 pips, Fractional pricing will yield 20 for its spread when you use MarketInfo-MODE_SPREAD. therefore you just need to divide the returned number by whatever xecn is.

btw, fractional pricing can also have 3 decimal places (refer to USDJPY) which Fulltime247 code snipplet already caters for.

Sorry, yes, that is what I meant, I was referring to an Indicator and an EA in the same statement. I'm running an indicator showing Spread values and so if I want to Display a Spread of 2 I would need to do a /xecn in the Indicator code so the returned value of 20 Displays a 2 but in the EA if I input that I don't want to trade if Spread is higher than 2 then that would actually mean 20 in a 5 Digit broker so I still need to do a *xecn if I put a 2 into my EA inputs to actually change that 2 to a 20 internally.

There's always 2 ways of looking at this.
you opt to change your input before comparing with the broker's returned value by multiplying your input value.
I opt for changing the broker's returned value before comparing with my input by dividing the broker's returned value.

I feel a better practice is to standardize your code logic. make it a point to always divide MarketInfo returned Spread by xecn. And also always multiply MarketInfo returned Point by xecn.
