subject: Support and Resistance Lines [print this page] Conclusion: Support and Resistance can be used to execute trades. Keep in mind, that technical indicators are not gaurentees of profitable trades. In our examples above, we could've easily entered an unprofitable trade, and the pair could've moved to a third resistance or support line. In most cases, a third resistance line or support line won't be met. In some cases, a resistance line will be met, we enter a sell order trade, and the first support level won't even be met. So we usually set the take profit before the support line.
