This EA is designed for passing challenges of prop trading firms that allow HFT (High Frequency Trading). It will not work on live accounts due to slippage. You should also not use it during the funded stage, the payout will be declined.
It works only on the mentioned prop firms, challange types and symbols below on the listed broker servers. HFT is broker sensitive, so if they change their broker or the broker does changes on spread or slippage, it might stop working. The trading only takes place in the first minutes after the US cash market opens. The default setting should work. No set files are needed. The timeframe does not matter.
| Supported Prop Firms | Asset | Broker Server |
|---|---|---|
| Sure Leverage - EA Challenge | US30.x | SureLeverageFunding-MT5 |
| Irizone FX | US30.Z1 | FazoLiqidity-Server |
| We-fund - 1 step HFT Challenge | US30.w | WeFundMarkets-Live |
Other firms can be passed with the MT4 version. All other firms or live accounts are currently not supported.
Features:
- Stops trading when the defined profit target is reached
- Stops trading when the defined drawdown limit is reached
- Auto increase lot size when the EA has made the defined amount of profit
- Displays all settings and live status on the chart
- Optional US holiday filter (volatility too low)
- Auto detection of the trade starting time
No VPS needed, but the latency to the MT5 server should not be too high. I tested it with 150ms of latency and it worked. Latency above 150ms might also work, but it was not tested and is not supported.
Backtesting this HFT Strategy in MT5 does not work in all cases, also the EA is Broker sensitive and optimized for the supported prop trading firms, so the backtest might not be good on all brokers even if the live result would be great. Maybe you want to disable profit target in the backtest so that the EA does not stop after a few trades.
The EA does NOT use grid or martingale.
In most cases, the default settings should be good, but on some challenges you might want to change the "profit target in %". If you want to change some settings watch the youtube video "Settings and tips for HFT Prop Challenge Master" on my Youtube Channel or read the settings below:
| Setting | Explanation |
|---|---|
| Lot size mode | Options: auto_increase: Increased the lot size after every x% profit made. fixed: Uses a fixed lot size which you can configure in the next field "Fixed lot size" |
| Here you set the lot size you want to trade. This field is only considered if you choose "fixed" as the lot size mode. It is highly recommended to not use too large lot sizes and also consider the contract size of the asset. If the lot size is too large and the move in the market is very fast, you might fail your challenge by exceeding the maximum daily drawdown. |
| The value in this field is used to calculate the initial lot size. Please note that if you put in for example 3 that this does not mean that 3 lots are traded. It means that per 10k USD on the account 3 contracts are traded. If you have for example a 100k account on Nova Funding then it will trade 30 contracts. Since the contract size on Nova Funding is 1 the 30 contracts would be 30 lots. If you have for example a 200k account on KortanaFX then it will trade 60 contracts. Since the contract size on KontanaFX is 10 the 60 contracts would be 6 lots. The lot size which will be traded will be shown on the chart. This field is only considered if you choose "auto_increase" as the lot size mode. If you trade on supported brokers with the symbol XAUUSD+ instead of US30, please note that this contract size here is multiplied with the value in the field "Contract multiplier for XAUUSD+". |
| With this amount of contracts per 10k account size the lot size will be increased if the needed profit is reached for the increase. It is calculated with the same logic as mentioned in the "Start contracts per 10k". This field is only considered if you choose "auto_increase" as the lot size mode. If you trade on supported brokers with the symbol XAUUSD+ instead of US30, please note that this contract size here is multiplied with the value in the field "Contract multiplier for XAUUSD+". |
| If the value is set for example to 0.5 it means that for every 0.5% of profit (e.g. 500 USD on a 100k account) the lot size is increased with the defined step which is defined in "Step contracts per 10k". This field is only considered if you choose "auto_increase" as the lot size mode. |
| If the number of contracts has reached this value, no further lot size increase will be done. It is calculated with the same logic as mentioned in the "Start contracts per 10k". It is highly recommended to not use to huge lot sizes and also consider the contract size of the asset. If the lot size is too large and the move in the market is very fast, you might fail your challenge by exceeding the max daily drawdown. I do not recommend setting this value higher than the default. This field is only considered if you choose "auto_increase" as lot size mode. If you trade on supported brokers with the symbol XAUUSD+ instead of US30, please note that this contract size here is multiplied with the value in the field "Contract multiplier for XAUUSD+". |
| In case you trade the symbol XAUUSD+ on supported brokers, the values in the fields "Start contracts per 10k", "Step contracts per 10k", "End contracts per 10k" are multiplied with this value. |
| Daily loss limit mode (trailing, set less then challenge limit) | Options: percent: The EA stops trading if the daily drawdown in percent of the starting balance of this day is reached. USD: The EA stops trading if the daily drawdown in USD of the starting balance of this day is reached. disabled: Disable the daily loss limit mode (not recommended!) The daily drawdown is always calculated from the highest equity or balance (which was higher) and is trailing to not give away to much profit if the volatility is going out of the market. |
| If the value is set for example to 1.0 it means that after 1.0% of loss from the highest balance or equity on this day (e.g. 1000 USD on a 100k account) the EA stops trading until the next day. Also if you challenge has for example a daily drawdown limit of 4% you should not set this value to 4% or 3.9%. Please note that when you have huge lot sizes and a very fast market move, it might take some time to close the open position and the loss of this trade might be worser then you wish because of slippage and latency. I do not recommend values above the default. This field is only considered if you choose "percent" as daily loss limit mode. |
| If the value is set for example to 1000 it means that after a 1000 USD loss from the highest balance or equity on this day the EA stops trading until the next day. Also if your challenge has for example a daily drawdown limit of 4000 USD you should not set this value to 4000 USD or 3900 USD. Please note that when you have huge lot sizes and a very fast market move, it might take some time to close the open position and the loss of this trade might be worser then you wish because of slippage and latency. This field is only considered if you choose "USD" as daily loss limit mode. |
| Profit Target mode | Options: percent: The EA stops trading if the profit target in percent of the starting balance of this challenge is reached. USD: The EA stops trading if the profit target in USD of the starting balance of this challenge is reached. disabled: Disable the profit target mode (ony recommended for backtesting) The profit target is always calculated based on the "Challenge size", see next input field. |
| If the value is 0 the EA tries to auto detect the initial balance. As an alternative, you can manually configure the challenge size (e.g. 100000 on a 100k challenge) in this input field. But please note that if you set the wrong challenge size, the profit target calculation in % will also be wrong. |
| If the value is set for example to 10.05 it means that after a profit of 10.05% of the challenge size (e.g. 10050 USD profit on a 100k account) the EA stops trading. This field is only considered if you choose "percent" as the profit target mode. |
| If the value of this input field is set for example to 10050 then the EA stops trading after a profit of 10050 USD. Also this input is only considered if the profit target mode is "USD". |
| Trading start hour mode (next input is ignored on auto_detect) | Options: auto_detect: The EA will try to auto detect what value should be set as "Trading start and end time hour" (which is the next input field). In this case the next input field is ignored. If it cannot auto detect it, the start of the EA will be aborted. manual: The EA will use the value of the next inut field "Trading start and end time hour" as start and end time hour. |
| Trading start and end time hour (MT5 server time) | If the value is for example 16 it means that the hour in which trading starts is 16. Please note that the EA used the broker server time from the market watch, so it should fit to this time, not to your local time. Currently for all supported prop trading firms 16 is the right value for the opening of the cash market. This setting is only used by the EA if the "Trading start hour mode" is set to "manual'. |
| Trading start time minutes (MT5 server time) | If the value is for example 30 (and the hour is still 16) it means that the minute in which trading starts is 16:30. This setting is used always, not matter what is set as "Trading start hour mode". |
| Trading end time minutes (MT5 server time) | This value defines the minute when the trading ends, for example 45 means that the minute in which trading ends is 16:45. This is usually a good value because later volatility goes out of the market and the market moves are too slow for the EA to make profits. This setting is used always, not matter what is set as "Trading start hour mode". |
| Trading on US holidays (not recommended) | Options: false: The EA will not trade on US holidays where the Future market is open, but the cash market is closed. In these cases, the volatility is normally too low for this strategy. true: The EA will trade on US holidays when the broker provides quotes even when the cash market is closed (not recommended) |
| Comment for each trade | The text of this input field is written in each trade comment |
| Magic number | Here you can specify a magic number. It is not recommend to have other EAs running in parallel. |
| Max number of messages sent to broker per day (0 = unlimited) | If you set here a number above 0, for example 2000, the EA will stop trading on this day when he has sent 2000 messages to the broker. A message is every creation, deletion or modification of a order. If you do for example a demo test on IC Markets you want to limit this number because the broker will first send you automatic emails and if you don't do anything, IC Markets will also block your demo account. |
| Max number of opened positions per day (0 = unlimited) | In cases where a number greater than 0 is set, for example, 48, the EA will stop trading on this day when 48 positions were opened. Please note that when the market moves extremely fast and you have high latency, it could happen in rare cases that one position is opened more than set. So if you have, for example, a limit of 50, set it to 48 if you want to add additional safety. |
