Forex Signals and Money Management – Martingale Type Strategies
Author: nobelfinanceBy Adnan Kaleemi
If you want any success in trading, you will have to control your risk exposure. Money management simply means how much you are putting in each trade you are taking in terms of risk exposure and dollar amount. The standardization process of your trades comes from money management. Standardization does not mean that you will have every trade similar because every trade is different due to its nature or entry, exit and pattern used as a criterion. What standardization does is that it effectively keeps your risk level within the same parameters for every trade you take. If you want any progress in your trading, you will have to control your risk exposure.
How do you feel when you take a position of 10K lot with 100 pips of stop in EURUSD? The loss is 100 in dollar amount. What will your feelings be and how would you handle a position of 100K lot when your stop loss is 50 pips. In this case the dollar loss amount is 500. Of course there is more exposure to risk in the markets and a greater emotional response. In the second case, the stop in pips is half but just by increasing the position size, the dollar amount of loss increased five times. Now let’s see how can these two trades be standardize. This can be done only by position sizing. Use the money management calculator provided to you to do these calculations. Here is how you do it. Suppose the portfolio size is 5,000 dollars.
Your risk in each trade you take is 2%. In the account size box put the dollar amount of your total equity in the account which in this case is 5,000. In the risk per trade box put the 2 in the %age of my total account size. Entry let’s say is 1.1500 and stop is 1.1600 and the stop is 100 pips. This gives you a maximum loss of 100 dollars in the trade. This gives you a calculation of one mini lot size of your position for this trade. To use the second example, we will now use the stop of 50 pips. Entry will be same 1.1500 and stop will be 1.1550. If you are taking a position of 100K lot, by using the money management calculator, you can see you are risking 10% of your account size in this trade. This is very high.
To take a position of single 100K lot you have to bring the risk level down to 2%. This can be done in two ways. One, your stop should be 10 pips instead of 50 pips or if you can not change your stop size, then you have to wait till your account size increases to 25,000 if you want to keep the stop to 50 pips. At this point you have understood the importance of position size and lot size calculation. By keeping the risk exposure to 2%, you are standardizing every trade you are taking and regardless of how big the position is or the stop loss level, if you use these powerful techniques used by top traders, you will have a geometric growth in your account with controlled risk exposure and emotional response.
Martingale type of strategies state that as the value of an account is decreasing, the size of the following trades increase. As the account suffers losses, the trading size increase in order to cover the losses.
This type of money management strategy is practiced in gambling where the systems or the games are negative expectancy. No type of money management can change the odds of the game or change the expectancy of the system. A simple example is a coin flip.
You can bet on heads or tails. If you win you win 1$ and if you lose, you lose 2$. This is negative expectancy. If after 100 flips, you have 60 heads and 40 tails, you will win 60$ and lose 80$ netting a loss of 20$.
Although you won 60% of the times, your wins were half the size of your losses. However, by practicing martingale, you can increase your bet size after every loss to 2$ to win 2$, in this case if a streak of wins start, you can manage to come up as a break even player.
This type of money management is highly dependent on streak of consecutive wins. Classically, the gamblers or traders try to take advantage of the streaks in the game. However, this is not going to change the negative expectation of the game. Any losing streak lasting for long enough will chew up the capital.
The theory behind doubling of size of the bet is that eventually the losing streak has to come to an end. I do not recommend this method of money management in forex, stocks, options or any other type of trading. The risks are too great and there is a good chance that 4-6 or more losing trades will ruin the account.
There are other better money management techniques which are antimartingale in nature. This will be discussed further in my other articles on money management techniques here on ezine articles.
