in this picture, two arrows should produce two signals but my ea can't send, why?

As we don't see all your code it's difficult to say. You can print your buffers values to check and compare.

Thank

I print out these variables cache and I said before, is the same, at the time it should be sent the signal, but K / D value is wrong, but look program it is corrent, whether this is an bug in MQL5 do?

The question is a base question, is there a problem in checking bar time in below part?

```//--- Do we have enough bars to work with
if(Bars(_Symbol,_Period)<60) // if total bars is less than 60 bars
{
Alert("We have less than 60 bars, EA will now exit!!");

datetime New_Time[1];
bool IsNewBar=false;

// copying the last bar time to the element New_Time[0]
int copied=CopyTime(_Symbol,_Period,0,1,New_Time);
if(copied>0) // ok, the data has been copied successfully

Who can help me? Thanks in advance!

Thanks angevoyageur

i checked your another reply, may be you are right:  Yes, signal on closed candle is better, as signal on current can be false signal. Although there are traders who trade on open candle, probably with some filters.

i will try to test!

Indicators: Stochastic Oscillator

• An uptrend is made up of higher highs and higher lows. Traders can use Stochastics to find excellent risk to reward entries at those low support points in the trend.
• A downtrend is made up of lower highs and lower lows. Forex traders can use Stochastics to find excellent risk to reward entries at these resistance high points
• Stochastics can be used to alert a forex trader to either tighten stops, reduce the position size, or take profit once in a trend trade

By far, traders who trade in the direction of the predominant daily trend have a higher percentage of success than those who trade the counter trend. One of the biggest attractions of the Forex market it is characterized by long trends that afford traders the potential to make hundreds of pips if they have timed their entries with precision and used protective stops to limit risk.

But How Can Traders Find Where to Enter with a Risk for Maximum Gain?

The mantra, “the trend is your friend until it ends,” can be found in many trading books, but it seems that many forex traders have not made the trend their friend and in some cases, the trend has become the enemy. Rather than being on the receiving end of those pips afforded to traders who have correctly entered the trend, many traders have been on the “giving” end of the trade losing pips while fighting the trend.

As people have turned to online dating services to meet their ideal match, forex traders can turn to stochastics as a way of making the trend the their friend again.

In an uptrend on a daily chart, stochastics %K and %D lines moving below the horizontal ‘20’ reference line and coming back above the 20 line indicates that the profit-taking correction is coming to an end. The stochastic crossing up also tells us that buyers are beginning to enter the market again. In addition, this shows that there is good support.

How to Trade the Trend Using Stochastics

Patience is the name of the game when attempting to trade with the trend. Getting into the trend too early can expose traders to large drawdowns. Getting in too late reduces the amount of profit before the swing is completed.

Use the stochastics indicator to find that “Goldilocks” entry of not too early and not too late. Once a strong uptrend is found, wait for stochastics with the settings of 15, 5, 5 to move into the oversold region below the 20 horizontal reference line. Next, wait for the %K and %D lines to move back above the 20 line. Enter long with a stop placed a few pips below the last low. Set a limit for at least twice the size of the stop.

Once in an uptrend position, traders will attempt to squeeze as much profit as possible. Traders usually take profits on their open position or trail stops once stochastics moves into the overbought region. It is important to note that a forex currency pair can continue to make new highs even though stochastics is in the overbought region.

So next time you see a trend and you do not know how to make it your “friend”, let the stochastics indicator introduce you! Once these swings are highlighted by stochastics, stop placement becomes easier as well. stochastics crossovers in an uptrend can help you pinpoint your entries to join the major trend.

This is very good EA for newbies - for the traders who are learning Stochastic indicator about how it works. EA is trading on overbought/oversold levels of Stochastic indicator with the following parameters which were coded to be inside this EA:

• the parameters of Stochastic indicator which were coded inside this EA: 5/3/3
• overbought/oversold levels to be coded in EA: 80/20
ea_Stochastic_system - expert for MetaTrader 4
• "Advisor analyzes the readings of the indicator Stochastic has, signal for buying is the intersection of the main and signal indicator lines in the oversold zone, a signal for the intersection of sales is the main indicator and signal lines in the overbought zone."

The coder proposed set file for this EA so we may use this EA on EURUSD M15 timeframe according to this set file/parameters.

I backtested EA just to see how it works - please find backtesting results and some charts with the ideas about overbought/oversold levels:

Hi

I have recently encountered a problem regarding stochastic.

I trade with an EA I wrote myself. One of the conditions to enter a trade for sell is that Stoch Main at bar 1 < Stoch Signal Bar 1.

From the attached file for a GBPUSD, we can see that at 10:00, Stoch Main Bar 1 > Stoch Signal Bar 1, but a trdae for sell was open.

The formula I used for Stochstic is

double StochMain1T30 = iStochastic(NULL,30,10,10,3,MODE_EMA,0,MODE_MAIN,1); // T30 MODE_MAIN

double StochSignal1T30 = iStochastic(NULL,30,10,10,3,MODE_EMA,0,MODE_SIGNAL,1); // T30 MODE_SIGNAL

One possibility I suspect is that based on the above StochMain1T30 < StochSignal1T30, but this is not what we see on the chart.

Can help me explain the above?

I have called Oanda, the broker, they told me that the position was not open by them and it was open by the EA.

Thank you.

Theory Of Stochastic Processes : With Applications to Financial Mathematics and Risk Theory

This book is a collection of exercises covering all the main topics in the modern theory of stochastic processes and its applications, including finance, actuarial mathematics, queuing theory, and risk theory.

The aim of this book is to provide the reader with the theoretical and practical material necessary for deeper understanding of the main topics in the theory of stochastic processes and its related fields.

The book is divided into chapters according to the various topics. Each chapter contains problems, hints, solutions, as well as a self-contained theoretical part which gives all the necessary material for solving the problems. References to the literature are also given.

The exercises have various levels of complexity and vary from simple ones, useful for students studying basic notions and technique, to very advanced ones that reveal some important theoretical facts and constructions.

This book is one of the largest collections of problems in the theory of stochastic processes and its applications. The problems in this book can be useful for undergraduate and graduate students, as well as for specialists in the theory of stochastic processes.
