I want a simple way to calculate lots size and profit; There is no simple calculation when equity, stop loss and required risk are - MQL4 and MetaTrader 4

Don't change that part of code. That part of code is checking if your broker is 4 or 5 digit broker. Also, here is a test using a $500 for initial deposit (risk 5% stop loss 20 pips, EURUSD used for test) and it works even with that initial deposit too

Hi, Mladen.

Yesterday, have asked you about the order coding.

But it too Complex.

I'm sorry, because i want a simple coding.

Just like this:

Account balance $500

with a 5% risk , open lots= $0.25

lots=$500*(risk/100)

lots=$500*(0.05/100)

lots=$500(0.0005)

lots=$0.25

Just liked this EA auto open a $0.25 lots.

And the lots count don't Mixing with Stoploss or TProfit.

I hope you can help me to solve this problem.

Thank you very much.

There is no simple(r) way to calculate lot size when equity, stop loss and required risk are taken into account. Also, you can not calculate the risk without knowing the stop loss (think about it : if you open an order, let say, size 1 lot and you close that after 1 pip or you close it after 100 pips the losses (and that way the risk that was taken) are not going to be the same and they can not be the same).

If you calculate it like that (without a known stop loss) then it is not the risk calculation but a simple lot size calculation (which does not imply any kind of risk calculation)

Mladen, you are right.

I know It does not imply any kind of risk calculation.

and just want a simple lot size calculation,

let it auto calculation lot size with the account balance with %.

lots=$500*(risk%/100)

lots=$500*(0.05/100)

lots=$500(0.0005)

lots=$0.25

Just liked this EA auto open a $0.25 lots.

And the lots count don't Mixing with Stoploss or TProfit.

How to coding it?

Thanks.

Thank a lot to mladen, i think is similar to what in my mind#1579, by the way, is it possible to convert DPO in the similar way as RSI or MFI equations normalize the vertical scale?Detrended Price Oscillator - MQL4 Code Base, thanks again.

Once when you have a template not difficult

Here is a rsi of a dpo. Upper is DPO and lower is the RSI of a DPO

hi mladen, i got your rsi of macd before, is it made with similar ways/logic as these recent force index FI and DPO ones?

i have attached your new rsi versions made recenlty(FI and DPO) on my computer, i encounter a problem if i use icustom function to recall their output values, it is not from 0 to 100 as show on chart but from -100 to 0 to 100, any comments of why, is it i refer recall wrongly the inside buffer value? thanks for advice.

when the buy order open price move to Reverse direction and Distance market price over 25 point,

it auto open a buy order again.

How to coding this strategic?

Thanks.

That code will not compile (replace OP_Buy with OP_BUY) and I do not see at all any conditions for an opening of another order. Per moment you are allowing only one order (the "if (TotalOrders<1)" line) That should be your starting point

CCI fdoe hpp

I downloaded this indicator from one of the threads and it is far better than the CCI-zones or Ma-zones indicators.

Can it be adapted to show on the screen as in a zone indicator?

It is set to CCI setting 13 but if it can be made into a variable setting indicator easily then that would be a bonus - but very much a secondary request.

It is a Forex-TSD indicator but no mq4 folder was with it.

Thanks
