I am a little bit silly today, buy what should I do? - MQL4 and MetaTrader 4

sunshineh 2013.02.11 13:39 #81

Thank you very much!

Perhaps I am a little bit silly today, buy what should I do, if I have noch stopLossDistance? Because I want to say absolut, that f.e. 5% of all my money on the account can be risk for the trade.

sunshineh,

Try using this function :

double getLots(string symbol, double Risk, double stopLossDistance)

{

RefreshRates();

double lots = 0;

double MinLots = NormalizeDouble(MarketInfo(symbol,MODE_MINLOT) ,2);

double MaxLots = NormalizeDouble(MarketInfo(symbol,MODE_MAXLOT) ,2);

double LotStep = NormalizeDouble(MarketInfo(symbol,MODE_LOTSTEP),2);

int LotDigit = 2;

if(MarketInfo(symbol,MODE_DIGITS)==3 || MarketInfo(symbol,MODE_DIGITS)==5) stopLossDistance *= 10.0;

//

if (LotStep==1) LotDigit=0;

if (LotStep==0.1) LotDigit=1;

if (LotStep==0.01) LotDigit=2;

if (Risk>0)

{

if (AccountBalance()>AccountFreeMargin())

lots = NormalizeDouble(AccountFreeMargin()*(Risk/100.0)/(stopLossDistance*MarketInfo(symbol,MODE_TICKVALUE)),LotDigit);

else lots = NormalizeDouble(AccountBalance() *(Risk/100.0)/(stopLossDistance*MarketInfo(symbol,MODE_TICKVALUE)),LotDigit);

}

//

lots = NormalizeDouble(NormalizeDouble(lots/LotStep,0)*LotStep,LotDigit);

lots = MathMax(MathMin(lots,MaxLots),MinLots);

return(lots);

}

You must know the stop loss. Without a known stop loss, you can not calculate the lot size using only the risk. Just a simple example : what would be the maximum price that can be reached if you, for example, open a sell position? So, stop loss is used to calculate what amount (in %) would you allow to loose if the price goes against you for stop loss pips

Hi all, is it possible to create Gann HiLo Activator using classic rsi (or) iRSI function or if such an indicator already exists.

Good Day everyone.

Gann high low activator uses sma of high, sma of low and a close. Since rsi does not have a high and low (it is a single value indicator) what is your idea how would it be used to calculate Gann high low activator?

Did you try QQE? It is very similar to your idea and it uses RSI in calcuulation

Hi,

First, I hope I'm right in this thread - if not please tell me...

Second, I tried my success lawst year with manual forex trading - and blew my depot to hell

So, as I recognized that I could eleminate some problems (the ability to watch the market 24/7, control of emotions at a trade, to be forced to have a strategy and the possibility to backtest it) by reanimating my programming skills, I found myself here

And I have a problem with my first selfwritten ea.

I made an ea (VolaRider) which uses two indicators I've found (i guess in this forum...)

##_TEST_STD_DEV_04BIN.mq4 and SuperTrend.

The first one gives me a volatility based (I guess) signal to enter and to leave the market. I modified this indicator a bit, to give him the the variables over the ea.

The second one just tells me if theres an up- or downtrend, to decide if I should open a buy or a sell order.

If I got a signal to enter the market the ea opens several new orders in the same directions at a defined distance (Pyramide).

When the ea gets the signal to leave the market, all orders will be closed at once. The Stoploss is just the emergency exit.

I got several problems with this ea:

1. at the backtest the ea is damn slow. Do I made a programming mistake or why it behaves this way?

2. After I backtested the ea, I took a look at the graphical output. There I could see that it doesn't always entered or left the market when the signal came. I don't have a clue why...

Oh, the best results I have at 15m timeframe.

Could you give my a hand to improve a) my skills and b) my ea?

Thanks in advance...

Of the speed problem : ##_TEST_STD_DEV_04BIN.mq4 is having multiple lops, but one of them is calculating almost all bars on each tick (this loop : for(i = Bars - K_PERIODEN; i >= 0; i--))and that is quite sure slowing down your EA (even in real time, not just in back-testing) So, that indicator needs to be optimized for a normal work first (otherwise it will cause you some problems, even signals missing when it works on all bars all the time can be sometimes a result of that indicators CPU usage %)
