OrderSend Error 134 (No Enough Money)

Sometimes, especially during backtesting or in case of a badly designed expert advisor, the OrderSend Error 134 (or ERR_NOT_ENOUGH_MONEY) appears in the Journal log of your MetaTrader platform. In MT5 this error is called TRADE_RETCODE_NO_MONEY and has a code 10019. The reason for this error is the same for both versions of the platform — lack of free margin to execute the OrderSend function for the given position volume. The methods to solve this error are quite different (we won’t discuss the post-development method, which is to deposit more funds to your trading account).
In MetaTrader 4, you have to code your EA to perform the following check before executing OrderSend():

if (AccountFreeMarginCheck(Symbol(), Direction, Volume) > 0)

if (AccountFreeMarginCheck(Symbol(), Direction, Volume) > 0)

It will check how much free margin will be available after opening a position with the volume = Volume in a given direction = Direction. But comparing it with 0 isn’t a very good solution. One should pay attention to the broker’s stop-out level to consider the margin requirements:

if (((AccountStopoutMode() == 1) && 
(AccountFreeMarginCheck(Symbol(), Direction, Volume) > AccountStopoutLevel()))
|| ((AccountStopoutMode() == 0) && 
((AccountEquity() / (AccountEquity() - AccountFreeMarginCheck(Symbol(), Direction, Volume)) * 100) > AccountStopoutLevel())))

if (((AccountStopoutMode() == 1) &&
(AccountFreeMarginCheck(Symbol(), Direction, Volume) > AccountStopoutLevel()))
|| ((AccountStopoutMode() == 0) &&
((AccountEquity() / (AccountEquity() – AccountFreeMarginCheck(Symbol(), Direction, Volume)) * 100) > AccountStopoutLevel())))

This way we check the way your broker applies stop-out (absolute or relative level) and check if we’ll have enough margin after our next trade.
For MetaTrader 5 this condition would look like this (replace SYMBOL_MARGIN_LONG with SYMBOL_MARGIN_SHORT if you want to check margin before opening a short position):

if (((AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE) == ACCOUNT_STOPOUT_MODE_MONEY)
&& (AccountInfoDouble(ACCOUNT_FREEMARGIN) - SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_INITIAL) * Lots * SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_LONG) > AccountInfoDouble(ACCOUNT_MARGIN_SO_SO)))
|| ((AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE) == ACCOUNT_STOPOUT_MODE_PERCENT)
&& ((AccountInfoDouble(ACCOUNT_EQUITY)/(AccountInfoDouble(ACCOUNT_EQUITY) - (AccountInfoDouble(ACCOUNT_FREEMARGIN) - SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_INITIAL) * Lots * SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_LONG))) * 100 > AccountInfoDouble(ACCOUNT_MARGIN_SO_SO))))

if (((AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE) == ACCOUNT_STOPOUT_MODE_MONEY)
&& (AccountInfoDouble(ACCOUNT_FREEMARGIN) – SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_INITIAL) * Lots * SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_LONG) > AccountInfoDouble(ACCOUNT_MARGIN_SO_SO)))
|| ((AccountInfoInteger(ACCOUNT_MARGIN_SO_MODE) == ACCOUNT_STOPOUT_MODE_PERCENT)
&& ((AccountInfoDouble(ACCOUNT_EQUITY)/(AccountInfoDouble(ACCOUNT_EQUITY) – (AccountInfoDouble(ACCOUNT_FREEMARGIN) – SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_INITIAL) * Lots * SymbolInfoDouble(Symbol(), SYMBOL_MARGIN_LONG))) * 100 > AccountInfoDouble(ACCOUNT_MARGIN_SO_SO))))

It is quite complex compared to the MT4 version but it checks the same condition.
Registering with a Forex broker that offers a lower stop-out level is also a good option :-).
Update 2016-11-01: Thanks to Alexander Wait’s comment, I have corrected the formulas for account margin check.
