What TrendSpider trading bots actually are
A TrendSpider trading bot is a rules-based strategy that fires real orders to your connected broker when conditions trigger. There's no code; you build the rules in TS Script (or generate them via the AI Strategy Lab) and TrendSpider handles the execution layer.
This is the closest thing in the retail world to algorithmic trading without needing a developer.
Plan requirements
Trading bots are on the Advanced plan. With our SET25 code, that's $60.75/mo billed annually — versus $97/mo monthly. If you're going to automate, the annual savings pay for the upgrade.
Step 1: Build a strategy you trust manually
The single biggest mistake new automators make: deploying a strategy they haven't already traded by hand. Don't do this. The order:
1. Trade the rules manually for 30+ days, take screenshots, journal the results
2. Backtest the same rules in the AI Strategy Lab to confirm historical edge
3. Walk-forward test on out-of-sample data
4. Paper-trade the bot for 14 days with simulated execution
5. Only then go live with small size
If a strategy can't survive steps 1-4, it won't make money in step 5.
Step 2: Convert your manual strategy into TS Script
Easiest path: use the AI Strategy Lab. Type your rules in plain English; TrendSpider generates the TS Script automatically.
Example: "Long entry when SPY closes above the 20-day SMA on volume > 1.2x 30-day average. Exit at 8% profit or 4% stop. Maximum 1 position. Skip earnings weeks."
The Lab outputs ready-to-deploy TS Script. Read it carefully — make sure the AI didn't add any unexpected conditions.
Step 3: Backtest with realistic execution costs
In the Strategy Tester, configure:
- Slippage: 0.05% per side for liquid equities, 0.15% for less liquid
- Commission: $0 if using a $0-commission broker, $0.65/contract for options
- Spread: TrendSpider models bid/ask if you toggle "real spread"
Don't trust a backtest with zero costs — it's lying to you. With realistic costs, marginal strategies often go negative. Keep only the ones that survive.
Step 4: Connect your broker
TrendSpider supports 11+ brokers. The most popular for bot trading:
- Tradier — fast API, options-friendly
- Interactive Brokers — broadest market access, but more friction to set up
- TradeStation — futures + equities
- Webull — equities only, simple setup
In TrendSpider Settings → Broker Integrations → choose broker → authorize. Takes 5 minutes.
Step 5: Deploy with conservative position sizing
For your first live bot:
- Position size: 25-50% of what you'd trade manually for the same setup
- Max concurrent positions: 2
- Daily loss limit: -2% of account (TrendSpider has a built-in kill switch for this)
- Run hours: restrict to 9:30 AM-3:55 PM ET to avoid pre/post-market weirdness on first runs
Watch every trade for the first 2 weeks. You'll catch edge cases (slippage, halted stocks, weird fills) you couldn't anticipate.
Step 6: Monitor and iterate
After 2 weeks of live running, compare actual P&L vs. backtested P&L on the same trades. If the gap is < 10%, your model is good. If > 20%, your slippage assumptions were wrong — re-backtest with bigger slippage and re-deploy.
What we'd never automate
After running bots for years, here's what we keep manual:
1. Discretionary entries — if your "edge" can't be expressed as 3-5 boolean conditions, it's not a bot strategy.
2. Earnings plays — too many edge cases (gaps, halts, IV crush) for a simple bot.
3. News-event trading — bots don't read news. They react late.
4. Anything with > 10% per-trade variance — high variance + automation = blown account.
Bots are great for: trend-following, mean reversion, breakout systems with mechanical rules, and rebalancing.
The honest math on bot ROI
A well-built bot trading 3-5x per week with realistic costs and 50% win rate / 1.5R reward — typical realistic profile — generates 15-30% annualized return in normal market conditions. Drawdowns can hit 15%+. That's a real, achievable benchmark.
Don't expect 100% returns. If anyone promises that, they're selling something.
TL;DR
TrendSpider's trading bots are the most accessible no-code automation in retail trading. Combined with the AI Strategy Lab, you can go from strategy idea to live bot in an afternoon. Just don't skip the manual + paper trading steps before going live.
