While most of the components of a trading system may seem obvious, some are often overlooked. This checklist will help you ensure that there isn’t something you have left out when building a trading system. These components apply to manually traded strategies, but are particularly relevant for a trading bot.

1. Volatility and Trend Filters

Filters are not an absolute requirement, but many trading systems have them. A filter identifies the setup for a trade as well as the market conditions under which trades can be entered. A combination of volatility and trend indicators can be used to create filters that identify the right market conditions for a system.

Many algo-trading systems stop performing when market conditions change. You can save yourself a lot of frustration by identifying the market conditions under which a trading strategy does and doesn’t work and incorporating them into the strategy. If you can do that you will not have to lose money before you begin to figure out the right market conditions for your trading bot to perform.

2. Entry Criteria

Each trade needs a trigger or trading signal. This can be very simple, like a moving average crossover, or it can be quite complex, requiring confirmation. Before a trading signal is generated the current position needs to be checked, and the capacity to take on new risk needs to be calculated.

3. Exit Strategy and Trade Management

Most trading systems have a combination of exit strategies which together make up a trade management plan. Broadly speaking a trade is exited in one of three ways: the trade is stopped out at the initial stop loss level, a profit target is reached, or a trailing stop kicks in to protect an open profit.

Splitting the position up with multiple targets and exit strategies may not add to the long-term profitability of the system, but it can smooth the equity curve by protecting some profits while allowing a portion of the trade to benefit form extended moves.

Most automated trading software can accommodate fairly sophisticated exit strategies. It’s well worth making use of this functionality to smooth the equity curve.

4. Position Size

Position sizing can be very simple or can be quite sophisticated if multiple positions are held. If your system adds to positions it will need to be able to read the current position and the total account size to calculate the capacity to take on more risk.

Something many traders don’t pay enough attention to is the lot size of the instrument to be traded. The notional value of each lot will determine the minimum position size, which in turn determines the minimum account size that can be traded for the strategy. Often, when a back test is done using automated trading software a default position size of $100,000 is used. If, however, a smaller live account of say $10,000 is traded, the lot size may be too large. The minimum viable account size therefore needs to be considered during strategy development.

5. Instrument Universe

The list of instruments to be traded doesn’t need to be written into the code, but it is nevertheless a part of the strategy. If a trading bot simply doesn’t work for some instruments this should, if possible, be included in the code or noted somewhere as a reminder. This will stop you accidentally running the system on a currency pair or instrument where it is not profitable.

6. Time Frame

Again, the time frame can be applied when the EA is launched and doesn’t need to be written into the code. However, if you know a trading strategy is not suitable for certain time frames, it’s worth including this in the code or as a note to prevent the trading bot being run on a time frame where it has little chance of success.

Thinking through each of these elements when developing your trading strategy will ensure that there are no surprises down the line when your trading bot begins live trading.
